+--gameframe.util.ObjectPreserver
- All Implemented Interfaces:
- java.lang.Runnable
- public class ObjectPreserver
- extends java.lang.Object
- implements java.lang.Runnable
This class has methods to ensure that an object is never garbage
collected. It is very handy when using singletons (classes that
have one static reference to itself) as these might be garbage
collected in some Java runtimes.
