Call EGL file from Java application [message #1749525]

Hi,

I am trying to call my .egl file from a Java application. Is there any simple way to invoke the .egl from Java?. I'm trying something like this:

	
	EglModule module = new EglModule();
	module.parse(new File("modelToCode.egl").getAbsoluteFile());
        EglTemplateFactory factory = new EglTemplateFactory();
        File templateFile = new File("modelToCode.egl");
        EglTemplate template = factory.load(templateFile);
        module.execute(template);

I have tried the standalone example but it is not working.I have also seen other examples with a call like module.execute() without any parameters ...

I really appreciate any help you can provide.

Hi,

The following should do the trick.

EglTemplateFactoryModuleAdapter module = new EglTemplateFactoryModuleAdapter(new EglTemplateFactory());
module.parse(new File("modelToCode.egl"));
System.out.println(module.execute());

If you wish to orchestrate more than one templates you may want to use EGX [1].

Hi Dimitris,

Thanks for your response, unfortunately it doesn't works.

The error is the next:
Exception in thread "main" Method 'generate' not found for: org.eclipse.epsilon.egl.EglTemplate@2d6e8792
at (....modelToCode.egl)

The modelToCode.egl code is the next:

[%
var main: Template := TemplateFactory.load('main.egl');
main.generate('../gen/main.c');
%]

Any suggestion?

Does switching

new EglTemplateFactoryModuleAdapter(new EglTemplateFactory());

for

new EglTemplateFactoryModuleAdapter(new EglFileGeneratingTemplateFactory());

work?

Cheers,
Dimitris

No, it doesn't work

Exception in thread "main" Type 'Graph' not found

How can I add my model to the adapter?

Thanks again.

Hi Juan,

That's much better; now all the parsing stuff works. I'd suggest having a look at [1] to see how you can load models and make them available to Epsilon programs.

Cheers,
Dimitris
