VersionedPut Class Reference

#include <coherence/util/processor/VersionedPut.hpp>

Inherits AbstractProcessor.

List of all members.


Detailed Description

VersionedPut is an EntryProcessor that assumes that entry values implement Versionable interface and performs an InvocableMap::Entry::setValue operation if and only if the version of the specified value matches to the version of the current value.

In case of the match, the VersionedPut will increment the version indicator before the value is updated.

Constructor & Destructor Documentation

VersionedPut ( Versionable::Handle  hValue,
bool  fAllowInsert = false,
bool  fReturn = false 
) [protected]

Construct a VersionedPut that updates an entry with a new value if and only if the version of the new value matches to the version of the current entry's value.

This processor optionally returns the current value as a result of the invocation if it has not been updated (the versions did not match).

Parameters:
hValue a value to update an entry with
fAllowInsert specifies whether or not an insert should be allowed (no currently existing value)
fReturn specifies whether or not the processor should return the current value in case it has not been updated
