a problem with wrappers which have parameters [message #1225555]

Hi,
I wanna write a wrapper with java but I have a problem when I want to add a parameter.
In following code the function TestCheck works but TestCheck2 doesn't work.
what should I do? The compiler says that "... doesn't exist for service ..."
Thanks in advance

------------------------------------------
package AUTCPP.javaWrapper.files;
import org.eclipse.uml2.uml.*;

public class Test {

public boolean TestCheck (Boolean t) {
return t;
}

public boolean TestCheck2 (Boolean t, StateMachine aSM) {
return t;
}
}
-------------------------------------------

Hi

"what should I do?"

Provide enough information so that we know what on earth you are talking
about.

This is the M2T newsgroup. Are you using Xpand/Acceleo/... ?

How do you invoke your code?

What does "doesn't work" mean? Did your machine catch fire?

Regards

Sorry

I am using Acceleo.
I create a .mtl file from .java file and call the queries inside of a template. The following code shows the .mtl file. As I mentioned TestCheck works but TestCheck2 doesn't work.

-----------------------------------------------------------
[comment encoding = Cp1252 /]
[module test2('http://www.eclipse.org/uml2/4.0.0/UML')/]

[query public TestCheck(arg0 : Boolean) : Boolean
= invoke('AUTCPP.javaWrapper.files.Test', 'TestCheck(java.lang.Boolean)', Sequence{arg0}) /]

[query public TestCheck2(arg0 : Boolean, arg1 : StateMachine) : Boolean
= invoke('AUTCPP.javaWrapper.files.Test', 'TestCheck2(java.lang.Boolean, org.eclipse.uml2.uml.StateMachine)', Sequence{arg0, arg1}) /]
------------------------------------------------------------

I don't know when I add some parameters form UML metamodel, this issue happens. The indicated error is shown in eclipse environment when I call TestCkeck2 in a template.

Thanks

HI

You might care to note the advice in
http://wiki.eclipse.org/OCL/ForumNetiquette

Your code looks sensible, but it is very confusing to have to guess at
all the information you don't provide.

This is my Java code :
------------------------------------------
public boolean TestCheck2 (Behavior bh, StateMachine aSM) {
for (Region rg : aSM.getRegions()) {
for(Vertex vt : rg.getSubvertices()) {
if (vt instanceof State && ((State)vt).getEntry() == bh ) {
return true;
}
}
}
return false;
}
------------------------------------------
I do following steps:
1) I create a .mtl file with the Acceleo wizard.
2) Import the created .mtl file inside of other files and call the quesry.
However, it doesn't work. I have other wrappers but they work( I have aleady existed). I think I miss something like adding a wrapper to somewhere.
The process is easy but I don't know why it doesn't work.
BTW, I added my project to new workspace in Eclipse and I compiled it, it worked but as soon as I changed it and created a new .mtl file it didn't work.
It shows me that I should do sth to tell the compiler which this is new .mtl file or sth like this.
I hope this makes clear.
Thanks

Hi

No it's as thick as mud.

You provide no repro of what does or doesn't work.

You don't identify any software versions.

You give no clarification of what "doesn't work" means.

Hi

I've added a "Rationale for not relying on telepathy" to
https://wiki.eclipse.org/OCL/ForumNetiquette. Perhaps it will help you
to help yourself.

I think there is no more thing to be said.
Everything is clear.
I just want to know how to write a wrapper with parameters from UML metamodel.
Indeed, I want to know exact steps for doing this.

BTW, This is a complete information

----------java wrapper------------
package AUTCPP.javaWrapper.files;

import org.eclipse.uml2.uml.*;

public class Test {

public Boolean CheckBehavior(Behavior bh, StateMachine aStateMachine) {
for (Region rg : aStateMachine.getRegions()) {
for(Vertex vt : rg.getSubvertices()) {
if (vt instanceof State && ((State)vt).getExit().getName() == bh.getName()) {
return true;
}
}
}
return false;
}
}
------------------------------------
-------------mtl file---------------
[comment encoding = Cp1252 /]
[module test('http://www.eclipse.org/uml2/4.0.0/UML')/]

[query public CheckBehavior(arg0 : Behavior, arg1 : StateMachine) : Boolean
= invoke('AUTCPP.javaWrapper.files.Test', 'CheckBehavior(org.eclipse.uml2.uml.Behavior, org.eclipse.uml2.uml.StateMachine)', Sequence{arg0, arg1})
/]
------------------------------------
--------the part of used code-------
[template public generateSMEntries(aStateMachine : StateMachine) post (trim())]
[for (aRegion : Region | region) separator ('\n')]
[if (subvertex->filter(State)->select(entry->isEmpty() = false )->size()>0)]
[for (aState : State | subvertex->filter(State)->select(entry->isEmpty() = false )) separator ('\n')]
[generateSMEntry(aState.entry)/][/for]
[/if][/for]
[/template]
-------------------------------------
----------------error----------------
Method CheckBehavior(org.eclipse.uml2.uml.Behavior, org.eclipse.uml2.uml.StateMachine) doesn't exist for service AUTCPP.javaWrapper.files.Test.
-------------------------------------

Is there any missing thing?
Thanks
