@ThreadSafe
public interface JCGLReferenceContainerType

The type of resources that can contain other resources.

This is primarily used to track resources that can be deleted: When an object is deleted by the programmer in OpenGL, the storage for an object X is only deleted if there are no other non-deleted objects that have references to X.

As an example: Assume a non-deleted array object A and a freshly created index buffer I that is not referenced by any other object.The programmer binds A, and then binds a non-deleted index buffer I. A now has a reference to I. If the programmer deletes I, the underlying storage for I will not be deleted until the programmer either unbinds I (breaking the reference) or deletes A (destroying the container).
