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.

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.
