[forge-dev] [forge-users] Get a list of all classes extending a specific class

[Rudy De Busscher]

Lincoln,

I created yesterday something simple

    public void visitSources(JavaSourceFacet facet, ClassVisitor visitor) {
        visitSources(facet.getSourceFolder(), visitor);
    }

    public void visitSources(Resource<?> searchFolder, final
JavaResourceVisitor visitor ) {
        if (searchFolder instanceof DirectoryResource) {

            searchFolder.listResources(new ResourceFilter() {
            @Override
            public boolean accept(Resource<?> resource) {
                if (resource instanceof DirectoryResource) {
                    visitSources(resource, visitor);
                }
                if (resource instanceof JavaResource) {
                    visitor.visit((JavaResource) resource);
                }

                return false;
            }
            });
        }
    }

public interface  JavaResourceVisitor  {

    void visit(JavaResource javaResource);
}


Regards
Rudy
