[acceleo] check for already generated java code [message #726888]

Hi

I would like to know if this is feasible.

I am generating java code from a model.

I can´t check beforehands if the method I am generating already exists in the code.

For example, suppose something like this

[for (aJavaMethod : JavaMethod | aJavaClass.javaMethods)]
[aJavaMethod.gen()/]
[/for]

If my java method is something like

[template public gen (aJavaMethod : JavaMethod) ]
public void [aJavaMethod.name/](){}
[/template]

How could I check if I am not trying to generate an already existent method? (solutions such as adding model validations won´t help me because the real situation I have here is quite complex, this example is only for me to explain the problem)

TIA

Kenji

Hi,

You would have to create a Java service to check "manually" but on the other hand you may be able to handle your problem with JMerge based tags. If you are not familiar with JMerge, you can have a look here.

Hi Stephane

thanks for the suggestions.

but I still have a doubt.

let´s suppose I try something like this

[for (aJavaMethod : JavaMethod | aJavaClass.javaMethods)]
[if (checkForExistentMethod(aJavaMethod))]
[aJavaMethod.gen()/]
[/if]
[/for]

on each iteration of aJavaMethod.gen() (an acceleo template method), the code is changed or all the changes are buffered in memory to be applied only in the end of the [file] directive? If it´s the second option, I guess there´s nothing I can do.

TIA

Hi,

The file is generated only at the end of the "file" block but while you are generating your code you can still have a look at the previous version of the generated file.
