My > question is: What is the difference between them? These are very big questions... here's a shot at it, but I think it will leave you wanting: A UDF is a function: it can be called (perhaps with defined input parameters) to do something. That's it: call it (maybe giving it something to work with) and get an answer (or some work done). Functions generally represent a task, a verb: Find(), Replace(), Delete(), etc - these are all functions. Functions tend to be generalized: I can call "Find()" all over the place, in all sorts of code and use it. The function doesn't maintain state, it's not persistent and it's not picky - it just works on what its given. A CFC is an object (OO people might slap me for saying this but it stands up well enough at a glance). Objects "know" things (data) and can "do" things (methods). CFC methods (those things that the CFC can do) are actually UDFs - so CFCs can also be seen as collections of variables and UDFs. However the UDFs in a CFC are usable only in relation to that CFC. So, in this way at least, CFCs and UDFs aren't in "competition". CFCs generally represent some thing. Some tangible (or virtual) noun. For example you might have a "Blog" CFC. This CFC might contain data (variables) containing the authoring information, system information, etc. It would also contain methods (UDFs) that helped you work with the blog. Things like "Add()", "Update()", "Delete()", "Display()", etc. > What are the pro's and cons to each? They are both very different things so it's not really a choice of using one or the other. However: On the plus side using CF Mappings CFCs (like Custom Tags) can be included in an application with no fuss and muss: once the mapping is made you access the CFC as if it were part of the language. CFCs also allow for more structured programming in CF (something often missing in CF applications). They don't really enforce better coding, but they can definitely lead to it. CFCs tend to be confusing to people that don't know OO (although they are the gentlest introduction to OO available). They are slightly more complex to plan for an write (since each CFC must be maintained in its own, separate file. UDFs are great for adding functionality to the language. CFML doesn't have a "CountMyToes()" function and you need it? No sweat: create a UDF. UDFs are also very fast in CFML. Since they are treated by CF as data (as are JavaScript functions) they can be copied, moved, sent, etc. Like CFCs UDFs can often lead to better code. For example you might have a complex calculation going on in an output loop. By moving that calc to a UDF you can greatly simplify the presentation code and separate the calc from your presentation. UDFs can also be a pain the butt as there is no server-level option for including them. You must, on the other hand, make sure to include them where you need them. Because of this UDF management can become a real chore. Unless some standards are put in place you'll find yourself getting those "cannot declare the same UDF twice" errors all over the place. > If I create a CFC with a several methods in it is that not the same thing > if > I have one template with the several functions on it? Is a CFC just a > collection of UDF's? In one sense: but it's much more than that. CFCs are very much like a CFM page in that they can have data (variables) and functions (methods defined as UDFs). However there are two key points: 1) CFCs can be created and run as a part of another page. As a contributor to the page. The CFC (unlike CFINCLUDE but like a custom tag) is a private memory area for things to happen it. 2) CFCs can be persistent. This is were the real power of use comes in. You can create a "Shopping Cart" CFC and store it in the session scope to be called on at any time. You can't do that with a UDF, Custom Tag or CFINCLUDE. Unlike a struct or array (which only "know" things) your shopping cart CFC can also DO things like "add()" or "calculateShipping()". > Does CFC use up more memory then UDF's? It depends on what they do and how they're used. There's no simple answer to this. Since UDFs cannot be persisted (saved in memory) then, in that sense at the very least, CFCs do take up more memory. In general since UDFs are generally used to do small, concise tasks they tend to be small and fast. CFCs tend to represent everything that some noun can be and do: they can get very complex and memory hungry. Going back to our examples you can create a "ShoppingCart" CFC that could have 20 methods (UDFs). But you'd be hard pressed to create a UDF that could do the same tasks as neatly. Lastly CFCs are often used a "function libraries". Some people find it easier to place a lot of re
RE: CFC or UDF
> What is the difference between them? A CFC is generally used to encapsulate portions of business logic into a reusable API that can be called by one or more applications in different ways. You can use a CFC to publish a web service that can be called from anywhere, or you can use it as a function library if you want to. A UDF would be used to define a method within a CFC, or it can be used to encapsulate reusable code in its own right. I have a UDF that validates e-mail addresses, for example. It gets included in a standard function library that most of my applications use, or it can be included in a CFC that might need that logic for some reason. There is a lot more than can be said on this topic, but that's what comes to mind here at a quarter to one in the morning. --- Justin D.

Re: Best practice question?
Johnny, Technically, yeah, that's exactly right. If you want to see all your scopes and all their contents, try this: That will dump every built-in scope, or those available to any page, special tag scopes notwithstanding, including: cffile cgi variables session application server form url client The other scopes, primarily, are (be kind, workin on the fly from memory here!): cfhttp cferror/error (similar but different, depending on cferror tag settings, see docs) query (addressed by queryName) cfcatch arguments parameters super thistag caller The first list are *always* available to any page, CFC, or construct of any type. The "variables" scope is the default container for any variables declared without being explicitly scoped in your code. So you're correct... args is actually variables.args. There are reasons to collect your form and URL vars into variables.args, though... it's a lot more convenient and allows you to build to an interface (i.e. args.action can be URL OR form, not restricted to either, doesn't matter which) rather than building to an implementation (MUST use URL or FORM, dependent on one or the other). You can use structAppend(args,url) and structAppend(args,form) to accomplish this, and the order in which you do this or whether or not you use the overwrite flag for structAppend is determined (in FB and MachII, and by developer choice in ad-hoc) by a variablePrecedence flag of form or url, determining which you know you can depend on to be in the args struct if there's a name conflict. All pages and CFCs have a variables scope and access as mentioned previously. However the other scopes, in the second list, are only available to code executing within the same context as the tags that create them (i.e. cferror is only available on an error page). So, if they occur within a function, they're available to the CFC. If they occur in a page, they're available to the page. If they occur in an include, they're available to the page after the include but not before. If you need to make the contents of a query scope that is created inside a CFC available to a page, you're going to have to use CFRETURN or cfset to a session, application, or some other mechanism to pass the query scope to the calling page. The other scope is the local scope, or the var scope, or function-local, that being a variable that dies as soon as the function in which it was declared, finishes executing... And, by "context" I basically refer to the owner of the current variables scope. Calling #args.maxCount# from within a container (like a page or a CFC) will, by default, refer to variables.args.maxCount. That's sort of what this thread is all about... is it acceptable to rely on the default scope for calling variables. Anyway, I hope that helps...

CFC or UDF
I am new to both of these features, but I am getting the hang of them. My question is: What is the difference between them? What are the pro's and cons to each? If I create a CFC with a several methods in it is that not the same thing if I have one template with the several functions on it? Is a CFC just a collection of UDF's? Does CFC use up more memory then UDF's? I am looking for best practice I guess. Sorry for the steam of thought email.

No - in the case presented (since the "var" keyword was used) "args" is in the "function local" (also called the unnamed scope). It is NOT in the variables scope and can't be accessed using it. The function local scope is persistent only during the current iteration of the function and is then gone. The variables scope is persistent to the instantiated life of the CFC (which can be quite a long time if the CFC is kept in a shared memory scope). The function local scope is the odd-man-out as to scopes: it's the only CF scope that's not named and not accessible as a struct. This is why I use . By creating this "pseudo-scope" and putting all of my function local vars into it I gain pretty much all of the benefits of other CF Scopes. But understanding the differences between the function local and variables scopes in CFC is tremendously important for building thread-safe applications. Knowing this stuff will save you tremendous heartache later - the bugs that come from this are nasty to track down and only appear under pressure.

Re: Best practice question?
This sounds great, but isn't the args variable has its own scope too? It is variables scope, isn't it? Since it declares locally in the function, I am not sure if its scope is variables, but it has a scope of something. So if you have scope everything, you would have to do variables.args.MaxCount, right?

That's why I like the way FuseBox handles input. So much so that I use it even outside my FuseBox apps. It takes all of the FORM and URL variables and moves them to the ATTRIBUTES scope if it doesn't already exist. That way you can CFPARAM all your input variables to that scope and use them wherever. You no longer have to worry about where they came from, AND you can continue to scope properly. Very nice, IMHO. --- Justin D.

Well it would have to be a page for which the Java classes created by CF for each CF template can't be reused... the only way I know to do that is to use or the like to write the template repeatedly and include it.

Iirc you can disable caching of the java classes in CF7 -- I don't remember off the top of my head if that's available in 6.1 ... though you're not generally going to do that in production either... so yes, there is a cost, but you pay it once and even then it's minimal at best. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://macromedia.breezecentral.com/p49777853/ http://www.sys-con.com/author/?id=4806 http://www.fusiontap.com ~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:200181 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54

Just to caveat your caveat one thing to be aware of with this is that the client-storage mechanism is set at the server-side, not programmatically. Unfortunately this means that depending the server configuration you may have size limits as well. For example even small data structures can make big WDDX packets: most of which are too big for cookies and some of which are too big the registry. Of course cookies and the registry are both the red-headed step children of client storage, but some people still use them. ;^) If you store your client information in a DB then the WDDX method works a treat (but you should still plan for performance testing as the conversion can be expensive if done too often).

I think we're saying the same thing - the QUERY is a two dimensional array, but the column is a one-dimensional array. The result from queryname["fieldname"] is a one-dimensional array, not two. > When using query["column"][rowNumber], you're effectively treating > your entire query as a 2-dimensional array, whereas you're asserting > that it treats the individual column as a one-dimensional array.

It does actually work just as I described (give it a try: query.column[1] will give you the value from that column for the first row of the query). Queryname["fieldname"][index] gives the exact same results as queryname.fieldname[index]. In this case (accessing a single cell) indexed and dot notation are equivalent and return the same values. However queryname.fieldname returns the value of the first row of that column while queryname["fieldname"] does not - it returns a one-dimensional array of all the values in the column. So in this case (accessing a column) indexed and dot notations result in different values.

It's still useful post-mx but just check out first.

Exactly - this also applies to structs as well (naturally since internally a query is a struct of arrays - the column name is the struct key). You can use indexed notation to use key or column labels that are not legal CF variables names (contain spaces as you mention but also begin with numbers, use odd punctuation characters or other odd things). All told the breadth and ability of CF variables and data structures far out-shadows any other language I've seen - but most people barely scratch the surface.

Seeking algorithm to calculate parallel processing cost
I am looking for a method to calculate the cost of running multiple, simultaneous processing jobs on a computer cluster. For example, I am renting cluster time at $XX/hour. I can run multiple jobs, but the cost is always $XX/hour regardless of the number of parallel, simultaneous jobs running. If one job is running I still get charged $XX/hour, or if 10 jobs are running during the same period, I still get charged $XX/hour. I have the start time/date and end time/date of each job. Anyone have any idea how to code this kind of calculation? TNX if you can provide some clues.

Right, query.column will get you the value, whether you're using cfquery or cfloop. Without a loop, you'll get the values from the first row of the query, which is a handy shortcut if you've got a one-row query. But, with cfoutput you DO NOT need to prefix the column, whereas with cfloop you do... perhaps not now, but in previous versions of CF you did. That's what Matt was referring to. > If you're not looping over a query then "queryname.fieldname" will always > return the value of the first row as if you said "queryname.fieldname[1]". > > The odd thing is with queries should you use indexed notation you get a > different value.

Well, yeah, it's true... but it's actually a 2-dimensional array, because your column name is the first dimension. I may be being unduly picky, but these are issues where "getting it right" is the same as "getting it to work." When using query["column"][rowNumber], you're effectively treating your entire query as a 2-dimensional array, whereas you're asserting that it treats the individual column as a one-dimensional array. It's a critical distinction, because query.column[1] should work as you've explained it, but it won't. > For most everything you can use this as an array.

And... something you don't see mentioned very often... this worked as far back as CF 4.x, it's not specifically a Java-derived feature, and I've used it on SQL Server datasets that had spaces in the column names because this treats the first dimension of the array - the column name - as a string, which, being wrapped in quotes, resolves just fine where #spaces in this name# won't work no matter how you try to resolve it.

Matt's right here, the basic rule doesn't change depending on scope, it changes on situation. If your looping over the query (with a cfoutput or cfloop using the query attribute) then doing "queryname.fieldname" will always output the current row's value. If you're not looping over a query then "queryname.fieldname" will always return the value of the first row as if you said "queryname.fieldname[1]". The odd thing is with queries should you use indexed notation you get a different value. While the value of "queryname.fieldname" is the value of the first row the value of "queryname["fieldname"]" is actually a reference the column - essentially a one dimensional array containing all of the rows values. For most everything you can use this as an array. To get the sum of a query column, for example, you can do ArraySum(queryname["fieldname"]). This is a very powerful feature - but test it first. CFMX had some minor bugs with this related to the fact that in some cases it counted the array from zero (as Java) and not from one (as CF). Just to plug much of this information comes from my guide to CFML variables. It's actually long overdue for a clean up (many of the links inside it are dead and some information has changed since CF 6.0) but it's still rather good if I do say so myself: http://www.depressedpress.com/DepressedPress/Content/Development/ColdFusion/ Guides/Variables/Index.cfm Jim Davis ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

Re: Best practice question?
You had to use the query name in cfloop but not in cfoutput. That's the only rule there was... at least that I recall... so this worked: #colName# And this worked: #qryName.colName# But this would only output the first row for every iteration: #colName# Laterz, J On Sun, 27 Mar 2005 15:06:43 -0500, Andrew Tyrone <[EMAIL PROTECTED]> wrote: > I might be crazy, but I seem to remember, at least in CF 4.x versions, that > if you scoped a query column within a cfoutput, it would only output the > data in the first row of the query, not the current row, no matter where you > were in the loop.

However, you would then be using pound signs unnecessarily, which indicates that you may be unsure when you need to use them and when you don't. An easy-to-remember rule for using pound signs in CF is that you only need to use them when you are getting the value of a variable and placing it into a literal string.

CFML isn't written especially like English, it's written like HTML. CFML is
designed to do one thing, and that's generate HTML. So, the creative minds
that came up with CFML explicitly modeled it after HTML. Many programming
languages, such as JavaScript, are not designed to do just one thing, and
programs written in these languages might be able to run in many different
environments. For example, JavaScript programs can run in an HTML page
within a browser, or as Windows Script Host files from a Windows command
line, or within a classic ASP page to generate HTML. So, the creative minds
that came up with JavaScript weren't so concerned with fitting it within one
niche.
I suspect that most programmers would rather shoot themselves than use a
tag-based language for things outside the niche of generating tag-based
markup like HTML, XML and so on. Most programmers learn programming with
languages that are more similar to JavaScript than CFML, too, and in many
respects those languages often give the programmer much more control over
how the program can work.

In general I would recommend just using the arguments prefix - as a CFC you should get used to verbosity (and clarity). ;^) But if you really wanted to do this you might consider something like this: You should now have a function local reference to the arguments scope in the args container. You can now use "args" in every way that you'd use "arguments". Easy peasy. Another trick I like is to do this: You can then easily set function local variables anyplace in the function (or at the top) by adding them to the "local" struct which becomes, essentially, a pseudo-scope. Putting all that together might look like this: #local.Cnt# It's a simple example but it's very clear where all the values came from and how each should be used.

Am I wrong? I might be crazy, but I seem to remember, at least in CF 4.x versions, that if you scoped a query column within a cfoutput, it would only output the data in the first row of the query, not the current row, no matter where you were in the loop. That might also have been the case when outputting query data with cfloop, and I might have these totally reversed as far as which exhibited the aforementioned behavior. Either way, I never scoped query columns when looping over a query for this reason. I don't remember with which version of CF this changed. Like I said, I might be crazy and this never was the case, but something tells me it was. Andy ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

Subject: Re: just noticed this when validating email
I do see your point... and further, I still disagree...
With all due respect, && is the AND comparison operator.
And == is the IS comparison operator.
My point was that JS isn't all that hard to read and write once you learn
it.
My new point is that if all languages were as easy to write as CF, the
world would be a very boring place. It's kind of like asserting that
the world would be a better place if everyone spoke English, and
nothing but English. Sounds kinda blah. Especially since other
languages contain idiomatic expressions that convey a nuance that's
impossible to convey in English, as English does with some things that
other languages don't.
+= would be a nice operator to have in CF... and yet it must be said
with i=1+1... hence some things are easier to write in JS than in CF.
And for me, often, I'd *rather* use JS-style syntax in CFSCRIPT. Why?
Because the JS syntax is more concise, and in general faster (though
CFSCRIPT no longer provides better performance per se, the concise
code it can produce reduces the code written under some
circumstances).
Also, your example isn't entirely fair, because you left out the whole
example in CF and wrote the whole example in JS:
#round(g[i][0])##calpercentage#%
And, if someone wanted to use cfscript for this task, it could be done
exactly as JS does it with very minimal alterations:
output = "";
while (i lte arrayLen(g)) {
calpercentage = round(g[i][1]*100/total);
calwidth = round(gwidth*(calpercentage*100));
output = output & "" & round(g[i][0]) & "" &
calpercentage & "%";
}
output = output & "";
writeOutput(output);
So, it's not so simple as CF is a more natural language... were it not
for Java, which looks almost exactly like JS, there WOULD BE no CF.
And had it not been for C++, which was the original language that CF
was written in, it would never have gotten started at all. CF is a
high-level productivity-layer language that works well for its
appointed tasks, and yeah, it might be great if everything worked that
way... but I doubt it. Since, if nothing else, there's a certain
amount of overhead that goes with turning human-readable code into
machine-executable code, there would probably be a huge cost involved
at runtime... whereas since CF is built in layers, the underlying
layers are very close to the surface and provide that conversion quite
quickly AND only once, in general, because it's only recompliled when
changes are made (generally speaking).
Anyway, I find other programming languages as fascinating as I do
other human languages, and think the landscape would be barren and
ugly without them.
Laterz,

Re: Best practice question?
But it IS a broad application-development question! You can't decide *not* to scope a variable until you know *why* you would scope one to begin with. You can't decide to rely on CF's default scoping capabilities successfully until you know all the implications of them. It is a broad app-dev question because the decision to use a particular technique must be founded in good app-dev skills. There's no getting around that. Explicit scoping _IS_always_ the best idea, unless you have a compelling rationale to break with the best practice.

Re: just noticed this when validating email
Typos, typos... i=i+1, for one... not i=1+1. And as far as preferring the JS-style syntax in cfscript, it's a style thing. It looks better and is less cluttered... I definitely use more tag-style code than cfscript, but I also use cfscript wherever I can simply to produce cleaner, more readable code.

RE: Best practice question?
That is definitely true, however, it can also be undesirable, for example a
developer might want form submissions to only arrive via post and not get.
I prefer to try to code using scopes and typically use something similar to
this in the case you mentioned (one may note that this is copied from
fusebox's functionality):
Function setAttributes() {
attributes = StructNew();
StructAppend(attributes,'form',true);
StructAppend(attributes,'url',true);
}
By explicitly declaring I'm choosing to use have both scopes together, I can
remove that ambiguity, and explicitly declare which scope I want to have
precedence while I'm at it.

>>I believe that scoping is important and removed ambiguity
Right, however, in some circumstances, ambiguity may be a useful feature.
For instance, not specifying the form or url scope for a variable can
make a template work both as a form action or as an href called template
with parameters passed in the url.

RE: Best practice question?
I believe that scoping is important and removed ambiguity, especially for developers (including yourself) who may latter have to work on that page. I would opine that scoping is a best practice. - Calvin -Original Message- From: Jim Davis [mailto:[EMAIL PROTECTED] Sent: Saturday, March 26, 2005 5:34 PM To: CF-Talk Subject: RE: Best practice question? > -Original Message- > From: Johnny Le [mailto:[EMAIL PROTECTED] > Sent: Saturday, March 26, 2005 12:33 AM > To: CF-Talk > Subject: Best practice question? > > Is it better to do this: > > >#Dept_ID# #CorName# #CorLevel# > > > or this: > >#GetCourses.Dept_ID# #GetCourses.CorName# #GetCourses.CorLevel# > When the examples are this simple it doesn't really show why you would do the latter - but in many cases the code between a CFOUTPUT can be very long and complex. It's almost always better to know where a variable came from. As for performance scoping a variable is almost always more performant - without the scope identifier CF has to do a scope chain lookup to determine where the variable is. Inside a CF output that scope chain look up begins with the query so it's still fast, but scoping is definitely not slower.
