com.tangosol.util
Class SegmentedHashMap.InsertAction

java.lang.Object
  extended by com.tangosol.util.SegmentedHashMap.InsertAction

All Implemented Interfaces:
SegmentedHashMap.EntryAction
Enclosing class:
SegmentedHashMap

protected class SegmentedHashMap.InsertAction
extends java.lang.Object
implements SegmentedHashMap.EntryAction

Action support for insert. The action performs locked insert, and is expected to run while holding the segment-lock for the specified key.

The context object for an InsertAction is the value object to insert in the map, or NO_VALUE to insert a synthetic Entry. The result of invoking an InsertAction is the (possibly synthetic) Entry object that was inserted for the specified key, or NO_VALUE indicating that a mapping for the key already exists in the map.

Constructor Summary
protected SegmentedHashMap.InsertAction()
           

 

Method Summary
 java.lang.Object invokeFound(java.lang.Object oKey, java.lang.Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket, SegmentedHashMap.Entry entryPrev, SegmentedHashMap.Entry entryCur)
          Invoke some action, holding the segment lock, when a matching Entry is found.
 java.lang.Object invokeNotFound(java.lang.Object oKey, java.lang.Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket)
          Invoke some action, holding the segment lock, when no matching Entry is found.
