Generating "void" methods using JvmTypesBuilder.toMethod. [message #756094]

I am trying to generate a method with return type "void" using the JvmTypesBuilder.

I noticed that the JvmTypesBuilder.toMethod takes a JvmTypeReference as parameter.
Simply passing "null" generates a method with returnType "void" but it automatically adds a return statement.
This is incorrect Java code and as a result is not compilable:

	public void test() {
	  return null;
	}

In the JvmModelInferrer I have the following:

	members += f.toMethod(f.name, null) [
		documentation = f.documentation
		for (p : f.params) {
			parameters += p.toParameter(p.name, p.parameterType)
		}
		body = f.body
	]

Passing a JvmVoidImplCustom doesn't work since this is not a subtype of JvmTypeReference.

What is the right way of generating a method with returnType "void" and without a return statement?

Thanks in advanced

Hi Goran,

you have to set void as the return type of the method, e.g. via
TypeReferences.getTypeForName(void.class, someEObject)
