java.lang.Object

org.wso2.siddhi.core.table.holder.IndexEventHolder

All Implemented Interfaces:

Serializable, EventHolder, IndexedEventHolder

public class IndexEventHolder
extends Object
implements IndexedEventHolder, Serializable

EventHolder implementation where events will be indexed and stored. This will offer faster access compared to other EventHolder implementations. User can only add unique events based on a given primary key.
