Enclosing class:

JavaPackage

static final class JavaPackage.BlankSlateWrapper
extends IncludedModuleWrapper

This special module wrapper is used by the Java "package modules" in order to simulate a blank slate. Only a certain subset of method names will carry through to searching the superclass, with all others returning null and triggering the method_missing call needed to handle lazy Java package discovery. Because this is in the hierarchy, it does mean any methods that are not Java packages or otherwise defined on the Java::JavaPackage will be inaccessible.

addSubclass

public void addSubclass(RubyClass subclass)

Description copied from class: RubyClass

Add a new subclass to the weak set of subclasses. This version always constructs a new set to avoid having to synchronize against the set when iterating it for invalidation in invalidateCacheDescendants.

Overrides:

addSubclass in class RubyClass

Parameters:

subclass - The subclass to add
