Description

Interface Summary

DynamicIndexCallback	This interface provides a callback mechanism for dynamic indexing process.
MapIndex	This interface is an abstract index that can be created on a Map.
MapIndexInfo	This interface is used to provide an index with detailed change information for a specific Map in a transaction.

Package com.ibm.websphere.objectgrid.plugins.index Description

This package contains the interfaces for the Map index related plugin framework.

Overview

Map index plugin framework provides a way to index cached objects for non-key search.

Implementing an index

Make a class that implements the MapIndexPlugin interface. This class will need to return an object that implements the index specific interface (such as MapIndex or MapRangeIndex) when the application asks the ObjectMap for a reference to an index. The com.ibm.websphere.objectgrid.plugins.index.HashIndex class is the built-in MapIndexPlugin implementation that can be used to configure on maps.
