Class TwoStageMap<K,V>
java.lang.Object
org.apache.cxf.common.util.TwoStageMap<K,V>
- Type Parameters:
K
- key typeV
- value type
- All Implemented Interfaces:
- java.util.Map<K,V>
public class TwoStageMap<K,V>
- extends java.lang.Object
- implements java.util.Map<K,V>
A Map backed by a limted capacity strong HashMap ("eden") containing
the youngest entries, overflowing into an unlimted WeakMapHash ("aged")
containing the older entries.
Used to avoid caching schemes being frustrated by over-agressive GC.
