Load classes in user project [message #638032]

Hi all,

I have this rule to let the user 'refer' to interface methods:

JavaMethodMap:
"maps to" javaClass=[types::JvmType|QualifiedName] '::'
javaMethod=[types::JvmOperation] ";";

I got scoping and linking working after a while but I got stuck in validation. I want to give validation errors if the referred jvmtype is anything other than an interface, so I wrote this code:

JvmType javaClass = javaMethodMap.getJavaClass();
Class<?> clazz = Class.forName(javaClass.getCanonicalName());
if (!clazz.isInterface()) {
...

The problem is that with that code I cannot load the classes that the user creates because "Class.forName" uses the classpath of the plugin, not the one of the project the user is working on.

I would appreciate any help.

Best regards.
Fernando.

Hi,

you don't need to load the actual class for that check (this information is stored within the JvmType-system). There may be a better way to do it, but the following might work for you.

Test whether your javaClass is an instance of JvmGenericType. If it is, you can make use of its isInterface method.

I didn't look any deeper in the JvmType hierarchy, but now I've found not only the method isInterface, but also access to all the interface methods, their parameters, etc.

Thank you very much Alex!
