Class SegmentedHashMap.InsertAction

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

All Implemented Interfaces:

SegmentedHashMap.EntryAction

Enclosing class:

SegmentedHashMap

protected class SegmentedHashMap.InsertAction

extends 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. <p/> The context object for an InsertAction is the value object to insert in the map, or NO_VALUE to insert a synthetic Entry. <p/> 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.
