[JBoss-dev] [Design of AOP on JBoss (Aspects/JBoss)] - Re: AOPC question on the inner src tag
As depends on first, all you need is only to compile needed plain _Java_
files - including aspects you want. Put then, every compiled *.class file into
your build directory and run on that directory.
Here snippets from my build.xml:
|
| target name=compile depends=common:read_params
| description=Java sources compilation
| javac
| destdir=${build.classes.dir}
| debug=on
| debuglevel=lines, vars, source
| deprecation=on

| nowarn=on
| optimize=off
|

| include name=**/*.java /
| src path=${src.main.dir} /

| src path=${src.aspects.dir}/transactions /
|
| classpath refid=compile_classpath/
| /javac
| /target
|
| !--
|| Weave all the sources with JBossAOP compiler
| --
| target name=aopc depends=common:read_params

| verbose=false
| classpath path=run_classpath /
| src path=${build.classes.dir} /
| aoppath path=${etc.dir}/jboss-aop.xml /
| /aopc
| /target

Of course you know, you may also use regular expressions inside jboss-aop.xml.
This might help.
And how many of those aspects, source files do you have anyway?
Or/and how much memory do you have?

[JBoss-dev] [JBossCache] - Re: Does node triggers coordinator methods?
Ok. I got this SharedStoreCacheLoader, but I have little problems with using it. It has strange constructor, so it cannot be plugged directly by using XML conf file. Any help with this, please? Next thing: about shared cache loader. Correct me if my assumptions are wrong: -I want to have shared DB -want to use lazy loading (my custom implementation) from DB -so I start cache with several nodes -aop tree is empty -tree.getObject(/customers/first); -after that, the tree has one element, loaded with my custom: Map get(Fqn fqn) method -I _thought_ from now on, in case every _other_ node wants /customers/first it will be given by cache -but: from other nodes method: Map get(Fqn) is still executed. So, basically: there is no cache ? :/ Here is my configuration: -FetchStateOnStartup: TRUE -CacheLoader: MyCustomLoader -CacheLoaderShared: TRUE -CacheLoaderPreload: empty -because I want to lazy load all data -CacheLoaderFetchTransientState: TRUE -CacheLoaderFetchPersistenceState: FALSE I think sth might be wrong with implementation of my CacheLoader. Because I think FileBased and Bdbje work correct. Any comment? T.

[JBoss-dev] [JBossCache] - Does node triggers coordinator methods?
Hi! I wonder whether when asking node (invoking 'getChildren()') for some objects, the method is realy executed on coordinator? I suppose it doesn't :( So what I try to achieve is to use my own persistence aspects - not CacheLoader. The scenario is: execute 'getChildren' on slave - this triggers 'getChildren' on coordinator - this triggers my lazy loading aspect - returns some results on coordinator - cache itself transfers data to slave nodes.. Is this scenario possible with JBossCache?

[JBoss-dev] [JBossCache] - Re: Does node triggers coordinator methods?
Yes, I want to write my own persistence layer, but let's say I want to do it
with 1.1, because that's last stable version.
Maybe I'll repeat problem in other words:
1) I want to cache Root object which may have some children: accessed through
'getChildren()' method.
2) I want to combine caching with lazy retrieving those data from database
using already written persistence aspect
3) I want only coordinator node to persist (retrieve, store) data.
4) I do not want to load whole data from database as the application starts,
but want to use lazy loading.
Problems occurs when application has started - no data loaded - and the first
node accessing data ('Root.getChildren()') is slave node. That's not the node
with persistence aspect applied. This node sees 0 data, because it wasn't
loaded by coordinator.
In other case, when the coordinator node access data first, it is loaded into
cache and distributed also to slave nodes. After that, slave nodes see data.
There would be no problem at all, if execution of 'Root.getChildren()' would
also trigger execution of the same method on coordinator. But this is as I
think impossible. Looking for some way of workaround for it..
Or more in generall: how to let the coordinator know that slave wants to
retrieve some data from underlying database, not from cache itself?
Hope it is enough.. hope for some tip

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: how to change the arguments of a method by AOP?
Hi
It works.
You must use execution joinpoint instead. It won't work with call joinpoint
as it doesn't make sense. Even if it works with AspectJ, when I think about
call type it looks strange to change called method's arguments from caller
context.
Is there some special reason you can't use execution joinpoint?
So your code should use MethodInvocation class instead, and binding should be
bind poincut=execution(void i$instanceof{SomeInterface}-someMethod())
:)

[JBoss-dev] [JBossCache] - get* and set* pointcuts vs. set(field) get(field)
Hi,
In TreeCacheAop doc you state sth like this: ..Whenever there is state change
('set*' interceptors)..All 'get*' operations..
I wonder if it is a good idea to restrict user of JBossCache to conform to some
getters-setters standard. Maybe it would be better to intercept field access
(read or write) using standard JBossAOP: get/set(field expression)?
You know there might be problems with settle(..) method for example, and
maybe someone (I :) ) doesn't like accessing their private implementation
through getters and setters..
I _think_ field access joinpoint would solve some problems..
How do you think? Maybe you have that in your plans for 1.2.
And one more thing: are you going to extract jbossCache as a concern, you
know.. to provide jboss-aop.xml bindings for jbossCache, for users who will
need some more advanced concern management?
Thanks in advance,
Tomasz Nazar

I've compared two approaches and I think it is impossible to realize your UseCase with JBossAOP. Comparing to AspectJ in field of introductions JBossAOP is quite weak. It is ..% pure Java and that's the reason. As I understood your case, you want some of your test cases to have different behaviour by not extending plain TestCase, but your custom MyTestCase, with custom 'setUp' and 'tearDown' methods for database connection initialization for example. AspetJ will simply put yout MyTestCase class between YourTestCase and TestCase in class hierarchy. This way you can use 'setUp()' method in YourTestCase and override it in MyTestCase.setUp(). With JBossAOP mixins it is not possible to achieve exact the same situation because of problem with: Caused by: java.lang.Exception: Mixin syntax.Base of pointcut | file:/jboss-aop.xml0 is trying to apply an already existing method setUp for | class syntax.Pojo When speaking about introductions: can someone give some answer why do we really need 100% pure Java in JBossAOP?

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: Different handling of XML entities between FINAL and RC1
Hi! No problem. But it's essential for me to have included entities. Say you have a product line and some already developed aspects, and want to include A, B, C concerns for configuration 1 of application, and only A and C for 2nd application. The only way, I think is to have two separate XML AOP files: config1-aop.xml and config2-aop.xml and manage concerns by including them using XML entities. Well, one could use some Ant's task to do this, but this is cleaner I think. So, this way it is possible to develop product lines with JBossAOP.

It was the same, when I wanted native after/before advice types in JBossAOP.
Of course in case of simple API - everyone's forgotten about that an interceptor can

Hello, I have the same problem with the difference that: -JbossCache 1.1 -standalone without anything else (JBossAS..) -adviced all the classes' fields with 'prepare' tag -have two different applications: Forum and Bank -both uses collections but Bank uses map.values() and a map where values consists of other collections (Lists) -Forum applications works OK *-Bank throws exception when putting into tree : ..IllegalArgumentException: get/set types differ Any suggestions? Is the problem related to lack of support for these collections' methods? Could you be more specific about overloading a call to a method, please?

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: AOP interceptor applied to all JSP/Servlet requests?
Hi. My penny to disscussion. I have Struts application and been using Tomcat server. I'd like to use JBossAOP with it. So what I've tried is: precompiled my plain servlets, jsps (in Struts meaning) with jasper/jspc. This way I got sources of my web pages for my application. As I have sources I can apply JBossAOP aspects to them - including crosscutting every Struts action and applying your own concerns (JBossAOP has some security concern @@org.jboss.aspects.security.*) I haven't tried to put compiled sources into Tomcat - but I think there shouldn't be a problem, as these are normal java classess. The only problem is: this way one looses favourite way of development. On every change of JSP we must recompile, redeploy whole app. :/ Solution would be to use somehow JBoss AS with Tomcat and dynamic classloader. I wait for some JBoss + Tomcat + Struts HOWTO. If there won't be any until September, I'll write one myself :) Regards, Tomasz View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3851730#3851730 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3851730 --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

It is not correct type of comparition. But thanks for sample. Let's have a closer look
at it, by first showing present state of JBossAOP API
| public void MyAspect

But true and useful Writer looks little different - it has write(String) method! (just
like number of other methods which don't give you additional funcionallity but help
you using other code)
| public java.io.Writer {
| void write(String str)

And I'm sure you don't use this writer.write(Open your eyes) and
System.out.println(And keep them opened) and you've written several emails to Sun

Yeah, nice to be on the second side of the mirror...

Hi Kevin! I was on short vacations, so forgive delay.. I'm impressed your patience for this topic. I've lost my energy for trying to explain why one needs 'before-after' types of advice. When you get fully functional code for emulation of before-after, send it to JBossAOP CVS, so other app developers can use it transparently - this is suggestion for JBossAOP authors, if you haven't noticed ;) Best regards, Tomasz Nazar PS.

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: Why lack of 'before' and 'after' advice types is bad..
Thanks for your time Kevin. Yes it works. I'm impressed. With your solution my 3DAspect looks simple. It's simple to configure it in way that you've provided. And my ExceptionHandlerAspect4D is a simple old JBossAOP aspect, with plain invoke(..). That's enough for me. Ok. But still it is a workaround, although smart and works for this example. But what about a whole aspect of before advice methods? To put, say persistance logic in one Aspect class. Not one separate interceptor for every core method (these 30 methods ;) ) . You know: beforeGetCustomers(), beforeRentAHouse(), beforeAnotherCoreMethod(), etc.. It isn't so simple now. You'll end up with 30 interceptors (extend AbstractInterceptor) or one aspect extending MyCustomAspect where you'll have 30 methods like this one... ouh my.. I'm scared of the code I see.. I won't write it... Wouldn't be it simpler to have: bind pointcut=execution(* Pojo-method1()) | interceptor class=knrc.beforeAfter.Aspect3D type=before / | | /bind | | aspect class=Aspect3D scope=PER_VM / | bind pointcut=execution(* Pojo-method1()) | advice name=beforeMethod1 type=before aspect=Aspect3D / | | /bind Thanks for explaining me this try()..catch()..finally() issues.

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Why lack of 'before' and 'after' advice types is bad..
Hi!
It's in my mind from some time. Now I share it with you.
Imagine situation of say, 3D concern which does sth before invoking core method. It's
applied directly on core classes (assuming OO is 2D)
Let's suppose someone wants to add 4th dimension concern directly on 3D concern. Its
aim would be to provide fault tolerance in a way, that if 3D concern fails, then we
should still keep running our core system, but without 3D concern applied.
To implement it in JBossAOP one must intercept all execution of advices of 3D concern
and surround it with some try()..catch() block.
3D concern (actual state):
public Object 3DAdvice(...)
| {
| if (doSomething());
| invocation.invokeNext(); - this is core method (2D)
| }
| }
Fault tolerant 4D concern (actual state):
public Object failTolerance4DAdvice(...)
| {
| try
| {
| invocation.invokeNext();
| }catch (SomeNastyException ...)
| {
| //continue running system... means proceed to the core method
| //which may be impossible with current JBossAOP
| ??? return invocation.invokeNextAfter3D(); ???
|
| }
| }
In AspectJ style and maybe with JBossAOP future style, one would use before advice
style for 3D concern..
3D concern (after/before state):
public Object before3DAdvice(...)
| {
| doSomething();
| }
Fault tolerant 4D concern (after/before state) then would be simple:
public Object failTolerance4DBeforeAdvice(...)
| {
| try
| {
| invocation.invokeNext();
| }catch (SomeNastyException ...)
| {
| //continue running system... means proceed to the core method,
| //means: do nothing because we are on before advice
| //and next invocation in chain is core
| }
| }
What do you say on that?
Or maybe there is some nice looking way for invoking invocation after next invocation
(which could solve lack before problem)?
Regards, Tomasz
PS. Anyway, emulation of after and before with around only is ugly.

Hi.
I was thinking a little about it and did some tests.
First you're right. That's way to achieve it in AspectJ. It could be sth similar for
JBossAOP in future.
Second: this solution implies that a developer who uses your AOP library _must_ know
AspectJ/JBossAOP syntax, etc. And this is not quite OK, and here is why I think so:
Imagine Jim, a developer of, say TicketsReservation system. Business logic for this
world is easy and simple. He prototyped his object world with POJOs only, so he has
nice running system with tests, and all of it, but these are only POJOs. He still
needs persistence, transactions, GUI.
And now is the time for him to think about it a little bit. Of course he finds PAT for
persistence ;) and some other AOP libraries for other services. But he doesn't know
nothing about AOP. He's heard from a friend but didn't write any aspect. And he don't
have to!
He wishes to annotate transactions, to annotate important business classes, _maybe_
adopt build.xml. But that should be all for him. Compilation (weaving), tests and
system runs.
So, what I'm trying to tell in this user story, is about some developer who only
wishes to use _our_ work. And it happens that our work is to develop set of services
for him. And that's great and for us and for him.
But for now, we have a problem, with order of aspects (AOP libraries) applied which is
still unsolved.
And I'm even not sure if Jim should know about problems with precedence at all!
What my idea is:existence of some known repository of known services and their
precedence priorities and relations to each other. Just like /etc/services has all
over the world known port numbers and names, in the same way, maybe there would exist
a list of such AOP libraries. But this is only idea and I don't think if it's even
realizable...
Another low level idea would be to give to our Jim sth like this one:
aopc -classpath aop-services/*.aop:$CLASSPATH$
| -Daop.precedence=persistence,transactions
| jim.bookingsystem.*
|
In this case both libraries must not use the same annotations names of course.
Ok. And back to reality: there is another related problem I've discovered today.
I thought that with this code:
/**
| * @@first
| * @@second
| * @@third
| */
| public int method1()
| {
| System.out.println(Method body.. :) );
| return 17;
| }
I will get:
[java] ==O==[main] FirstInterceptor: 28: @first: {}
| [java] ==O==[main] SecondInterceptor: 28: @second: {}
| [java] ==O==[main] ThirdInterceptor: 28: @third: {}
But that's not the case!
I got [java] ==O==[main] SecondInterceptor: 28: @second: {}
| [java] ==O==[main] FirstInterceptor: 28: @first: {}
| [java] ==O==[main] ThirdInterceptor: 28: @third: {}
|
because definition of poincuts in jboss-aop.xml file was:
bind pointcut=execution(* *-@second(..))
|interceptor class=SecondInterceptor/
|/bind
|bind pointcut=execution(* *-@first(..))
|interceptor class=FirstInterceptor/
|/bind
|bind pointcut=execution(* *-@third(..))
|interceptor class=ThirdInterceptor/
|/bind
And I must say I don't like it.
As a end user (Jim) I assume that the order of advices (defined by annotations) will
be the same as order of their definition in method's comment.
To be more verbose, I want @@securable before @@transactionable before @@persistable.
And as you see I prefer annotations as a way of specifying system concerns instead of
normal poincuts definition.
Best regards,
Tomasz

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: Annotate class only and crosscut methods within the clas
Yupiii!
And once more, I reply to my own post :)
So here is the solution with new TYPE_DEF feature:
jboss-aop.xml:
aop
| typedef name=rootable expr=class(@root) /
|
| bind pointcut=all($typedef{rootable})
| interceptor class=RootInterceptor/
| /bind
|
| !-- If you annotated class with @@root you don't need this
| annotation tag=root class=MyRoot
| class/
| /annotation
| --
| /aop
|
Interceptor:
public class RootInterceptor
|implements Interceptor
| {
| public Object invoke(Invocation invocation) throws Throwable
| {
| if (invocation instanceof ConstructorInvocation)
| {
| ...put logic here for Constructor joinpoints..
| }
|
| }
| }
|
and core code:
/** @@root */
| public class MyRoot
| {
| public void method1(){}
| public static void main(String[] args)
| {
| System.out.println(--START);
| MyRoot root = new MyRoot();
| root.method1();
| System.out.println(--END);
| }
| }
|
There is only default constructor here. But the logic from
RootInterceptor will be applied. That's great.
Output:
[java] --START
| [java] ==O==[main] RootInterceptor: 23: [EMAIL PROTECTED]
| [java] ==O==[main] RootInterceptor: 25: I'm in ConstructorInterceptor
| [java] ==O==[main] RootInterceptor: 23: MyRoot_method1_N4778546224999628736_

Hello The solution might be to package adviced and non-adviced classes in two different packages, and instead `*` use sth like: `bind ... com.mycompany.aoptized.*`. (unless you have quite complicated package tree) I don't know if syntax that you provide in the introduction is even supported. And btw, what do you need execution-of-everymethod for? You must have some real special requirements.. Hmm, as I think.. AspectJ's `within` might help, but JBossAOP doesn't provide it. One may use `all(com.MyClass)` instead.. t.

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Annotate class only and crosscut methods within the class
Hi all
During weekend heavilly developed (what? later :) ) with JBossAOP.
Question by the code:
package my.demo;
| /** @@my.root */
| public class RootClass
| {
| public RootClass()
| {
| //constructor here
| //...
| }
| }
|
| jboss-aop.xml
| bind pointcut=execution(my.demo.*-@my.root)
| interceptor class=RootCreationInterceptor /
| /bind
|
I want to crosscut every constructor of class that has only been annotated with tag
@@my.root for the class (not for the constructor).
I don't want to annotate _every_ constructor inside class (which works with JBossAOP).
I've also looked at tutorial at page about annotation introductions. It could also
work for me, if I can _introduce_ annotation to constructors, by specifying only tag
for the whole class. But annotation-introducionts seem not to work that way.
Sth like that, doesn't work:
| jboss-aop.xml:
| annotation-introduction expr=constructor(my.demo.*-new()) AND class(@my.root)
| @my.root
| /annotation-introduction
|
Although, above doesn't make sense, I think.
Are there any possibilities of solving my problem?
Thanks, for help :)
Tomasz

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Instrumentor makes _transient_ fields when introducing field
Hi,
Another separate topic after work at weekend.
I need my objects to be serialized. I also need to introduce Identificable
implementation to every of them, to give them OID. I did this by introducing
IdentificableMixin:
| public class IdentificableMixin...
| {
| private Long oid;
| private void setOID(...
| private Long getOID(...
| }
After logging few lost hours it happened that (by checking decompiled class) JBossAOP
introduces this mixin to the class as a field and makes it transient. Decompiled
sample:
|private transient IdentificableMixin
_my$demo$getOID$IdentificableStringMixin$aop$mixin;
|
Unfortunately for me it happend to be _transient_ which doesn't serialize. So my app
magically didn't work :/.
For my app I need mixin fields to be normal - not transient.
I found 2 places in JBossAOP code which I think are responsible for that:
jboss.aop.instrument.Instrumentor:
|
| private CtField addProtectedField(...
| {
| field.setModifiers(Modifier.PROTECTED | Modifier.TRANSIENT);
|
| private CtField addPrivateField(
|{
|
| field.setModifiers(Modifier.PRIVATE | Modifier.TRANSIENT);
I've removed Modifier.TRANSIENT, and all the fields (I think) that JBossAOP introduces
to classes are not transient.
So, I did this, but are there any reasons for them to be transient?
I know that you didn't realized that someone will use Mixins in that way.
So you see now (or will see in some days :) ).
Comments?
Tomasz

Ok. I figured it out after a while, and did as you said. Problem is with finding door: and it was building all jboss. So, thanks anyway. Let's go back to the problem. I compiled today's version of JBossAOP, and switched jboss-aop.jar only. Before the operation, everything (with `execution of public PreparedStatements.getConnection()) worked fine.

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - IllegalAccessException
Hi,
I think I have some configuration problem with j2sdk or sth similar, cause you say in
earlier thread and in docs, that it's normal to advice private class members.
This is part of my class, and method I want to advice:
| public class banking.aspects.persistance.PreparedStatements
| {
| private Connection getConnection(){ ... }
| ^
| ...}
|
That's part of jboss-aop.xml:
| aspect class=banking.jbossaop.transactions.DbConnectionAspect scope=PER_VM /
| bind pointcut=call(*
banking.aspects.persistance.DatabaseGateway-getConnection())
| OR
| call(*
banking.aspects.persistance.PreparedStatements-getConnection())
| advice name=switchConnection
| aspect=banking.jbossaop.transactions.DbConnectionAspect /
| /bind
|
And error from ant looks...
| run-static:
| internal:parametrisied-java:

Any ideas about sth wrong here?

Hi,
Of course it's impossible to run ...PreparedStatements.getConnection() within anywhere
except the class, cause it's private - except one would invoke it by using reflection,
which I don't.
But here is the aspect class, that I haven't provided before:
| public class DbConnectionAspect
| {
| private DbConnectionsHelper dbConnectionsHelper;
|
| public DbConnectionAspect()
| {
| dbConnectionsHelper = new DbConnectionsHelper();
| }
|
| public Object switchConnection(Invocation invocation)
| throws Throwable
| {
| invocation.invokeNext();
| return dbConnectionsHelper.getConnectionForCurrentThread();
| }
| }
|
As u see, I totally ignore returned value of invocation.invokeNext() which is my aim:
to switch global connection into per-thread connection (wchich allows one to program
threaded apps in non-threaded way :] )
I'll check these tests from CVS...

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: IllegalAccessException
Hi,
Problems with cvs compilation:
First: downloaded whole jboss cvs tree (default branch)
cd jboss-aop
build.bat dist
Second: In file: jboss-aop/build.xml line:
| fileset dir=${project.thirdparty}/xdoclet-xdoclet/lib
| is incorrect. There is no dir called xdoclet-xdoclet.
But I replaced with correct one, and then
removed 'javadocs' from target 'dist' cause of:
| [javadoc] D:\nthx\install\jbossaop\jboss-cvs-04.08.2004
| \AnnotatedPOJO.java:16: illegal character: \64
| [javadoc]@trace public int field;
| [javadoc]^
|
Then: `$move 'thirdparty/javassist/javassist ..` cause of:
| BUILD FAILED
| D:\nthx\install\jbossaop\jboss-cvs-04.08.2004\jboss-ao
| -cvs-04.08.2004\thirdparty\javassist\lib not found.
|
And the same with: oswego-concurrent, trove, qdox, junit,
And before that:
| mkdir ..\common\output\lib
| build dist
|
And thank-you JBoss fellows .. `build dist` built a jar file without classess.
`build jars` doesn't work.. problem with not-having other classess (jboss-common)
Sorry, but I've seen many build configurations and this isn't one..
Is this on purpose? This you call 'professional'?
Need help with writing ant files? People, wake up! It's becoming to be not funny...
As stated Scott Stark : Its baseline status requires nothing other than running the
jboss-head/build/build.xml script. That's the answer?
Please explain...

[JBoss-dev] [AOP on JBoss (Aspects/JBoss)] - Re: Pointcut expression for methods that take arrays as argu
Hi, there.
This is my first post after checking out JBossAOP, and implementing persistance and
transaction layer for my POJOs with it.
So ...
Is it possible to intercept element-of-an-array assignment?
I mean:
| //I'd like some code here (through Interceptor, of course)
| myArray[5] = newElement;
| //maybe I also would like some code 'around'..
| //maybe sth like this: myArray[5] = getCachedMyElement;
| //or even 'after': UPDATE OBJECT_TABLE WHERE ...
|
And the binding in jboss-aop.xml, would look like this:
| aop
| bind pointcut=array-element-set(myClass.myArray)...
| bind pointcut=array-element-get(myClass.myArray) ...
| /aop
|
If I had the functionality, then I would write persistance-layer with no limitations
on collections classes, or whatever limitations existing persistance layers may have.
More deeply: One would not write bindings for every collection class, i.e.
collection.add(), collection.get(i)
One would write generic persistance, by: intercepting
every-variable-change-including-array-element-assignment.
And the real example of this is: java.util.ArrayList, where it stores data internally
in an array:
| package java.util;
| public class ArrayList {
|
| private transient Object[] elementData
| ...
| public boolean add(Object o) {
| ensureCapacity(size + 1); // Increments modCount!!
| elementData[size++] = o;
| return true;
| }
| ...
|
I think you know what I mean now. I'd like to have simple
| bind poincut=array-element-set(java.util.ArrayList-elementData)
|
instead of binding, and implementing every collection class' method which manages
data.
PS. Of course AspectJ also doesn't have functionality mentioned above, either
