[forge-dev] JavaType vs JavaSource

[Antonio Goncalves]

Hi all,

I am having a look at some code and realize that I don't understand the
subtle difference between JavaType and JavaSource in certain cases. In some
visitor code (see below), I see :

JavaType<?> javaType = resource.getJavaType();

And other times I see :

JavaSource<?> javaSource = javaResource.getJavaType();

So I look at the code. JavaSource extends from JavaType, adds one method,
and then they both implement similar interfaces (JavaDocCapable vs
JavaDocCapableSource).

So, in the following example, why use JavaSource instead of JavaType ?

Thanks
Antonio

 @Override
            public void visit(VisitContext context, JavaResource resource)
            {
               try
               {
                  *JavaType<?> javaType = resource.getJavaType();*
                  if (javaType.isClass() &&
!javaType.hasAnnotation(Entity.class)
javaSource.hasAnnotation(MappedSuperclass.class))
                  {
                     classes.add(resource);
                  }
               }
               catch (FileNotFoundException e)
               {
                  // ignore
               }
            }
