Class SegmentedHashMap.InsertAction

java.lang.Object
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.

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.

invokeFound

public 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.

Specified by:

invokeFound in interface SegmentedHashMap.EntryAction

Parameters:
