Re: TapestryIoC: Is it possible to receive an OrderedConfiguration's ID?

[Eli Doran]

I started with wanting to create a Chain of service instances using an
ordered contribution point. Unlike usual though, the implementation isn't
custom each time. Instead, there's multiple repeat uses of an
implementation which does different work based on a String supplied it.
This String also happens to be unique to it and can be its ServiceId.

I was thinking I'd end up able to do something like this:


> orderedConfiguration.addInstance("SomeService",
>  PremadeRepeatUseImpl.class, "before:SomeOtherService,after:DiffService");

a different module...

> orderedConfiguration.addInstance("AnotherService", PremadeRepeatUseImpl.class,
> "before:SomeService");


What the PremadeServiceImpl class needs to know is the string:
"SomeService". I was hoping it could receive the ID because otherwise I
must create the instance manually and feed it the String.

My goal is to make it simple for a new Module to addin and contribute more
instances. One contrib method with one line and TapIoC autobuilds all the
instances and injects the desired params. Then the root Module uses the
contribs to build the chain with ChainBuilder.

Without it being able to learn it through some automatic means I ended up
with the below. It uses a builder method which uses its method name to
assign the service ID and constructs the instance directly. Then, inject
the built instance into the contrib method via InjectService and use add()
instead of addInstance():

public static PremadeInterface buildSomeService(..inject the constructor
> needs...)
>   return new PremadeServiceImpl("SomeService", provide needs...);


It works, but, use of the ID is repetitive and has some unsafe uses, like,
the method name, which can't use a constant value. And it looks a little
odd.

Answering the queston in the subject: no, it's not possible to receive an  
OrderedConfiguration id. Why do you want that?

Nothing specific that I know of...

...you could iterate over the ServiceActivities in the
ServiceActivityScoreboard service looking for a matching service
interface and take the ID from there. It's not nice, but as long as
you know the type of the service, it should work.

Found this Git 
changewhich
removed the "automatic injection of service id" from the
AbstractServiceCreator.java source file. There are corresponding changes
which remove the Inject annotation (as it's no longer necessary to override
the resource injection).

Is there a *new* way to cause the ServiceId injection?

[Eli Doran]

Also, in this 
sectionit
doesn't list String and service ID as a resource.

As a side note, if you look at the list item for ServiceResources it looks
like the last part should actually be a new list item. Anyone agree?

Re: TapestryIoC: Is it possible to receive an OrderedConfiguration's ID?

[Eli Doran]

Also, it seems the fourth example in this
section
doesn't
work with Tapestry-IoC-5.3.6 (service builder method in the module
accepting 'String serviceId' parameter).

Has this behavior changed in recent updates and the documentation is behind?

Re: TapestryIoC: Is it possible to receive an OrderedConfiguration's ID?

[Eli Doran]

Using a String param in the service implementation constructor causes a
RuntimeException stating "No service implements the interface
java.lang.String". It is mentioned in multiple places in the documentation
that a String type without the Inject or InjectService annotations will
receive the ServiceId  as a "Resource", but, I'm causing this exception
instead.

For an example below is a ServiceBinder call and the service implementation
constructor prototype.

serviceBinder.bind(ServiceIdAware.class,
> ServiceIdAwareImpl.class).withId("TestId");
>
serviceBinder.bind(ServiceIdAware.class,
> ServiceIdAwareImpl.class).withId("TestId2");
>

>
public ServiceIdAwareImpl(String serviceId)


Shouldn't that constructor receive the ServiceId specified in the withId
method?

No, but if your contribution is a service then you can inject the
ServiceId using the @Symbol annotation:

TapestryIoC: Is it possible to receive an OrderedConfiguration's ID?

[Eli Doran]

When using OrderedConfiguration the add method's first argument is an ID.
Is it possible to inject that ID into the corresponding instance's
constructor?
