TileLRUMember (Apache Batik Javadoc)

java.lang.Object
- org.apache.batik.ext.awt.image.rendered.TileLRUMember

All Implemented Interfaces:

LRUCache.LRUObj
```
public class TileLRUMember
extends java.lang.Object
implements LRUCache.LRUObj
```
This is a useful class that wraps a Raster for patricipation in an LRU Cache. When this object drops out of the LRU cache it removes it's hard reference to the tile, but retains it's soft reference allowing for the recovery of the tile when the JVM is not under memory pressure
