Class DelegatingValueFactory

java.lang.Object
  com.jrockit.memleak.util.DelegatingValueFactory

All Implemented Interfaces:

IMemleakValueFactory

Direct Known Subclasses:

InfoCachingFactory

public class DelegatingValueFactory
extends java.lang.Object
implements IMemleakValueFactory

A value factory merely delegating to another implementation of IMemleakValueFactory. Intended to be sub classed, like an adapter. There is little point in using it directly. (It isn't abstract, to make sure it implements all methods.)
