public class ReferenceCountedDelayedDestroy

extends java.lang.Object

A base class that supports reference counting and delayed destruction. Specifically, this class provides a destroy method that waits until the reference count becomes zero before returning. Subclasses of this class that need to perform class-specific destruction actions should do so by overriding the destroy method as follows:

public void destroy () {
    super.destroy();
    ...
}
