Class WeakishReference

java.lang.Object

org.apache.tools.ant.util.WeakishReference

Direct Known Subclasses:

WeakishReference.HardReference

Deprecated.

deprecated 1.7; will be removed in Ant1.8 Just use WeakReference directly.

public class WeakishReference
extends java.lang.Object

These classes are part of some code to reduce memory leaks by only retaining weak references to things on Java1.2+, and yet still work (with leaky hard references) on Java1.1. Now that Ant is 1.2+ only, life is simpler and none of the classes are needed any more. They are only retained in case a third-party task uses them

Since:

ant1.6
