- All Implemented Interfaces:
java.io.Serializable
public class InMemoryQueryIndirectionPolicy extends java.lang.Object implements java.io.Serializable
Purpose: Provide a means of controlling the behavior of in-memory and conforming queries that access un-instantiated indirection objects in processing the query against cached objects.
Description: This class defines the valid constant values for handling in-memory querying. The constants should be set into the query's inMemoryQueryIndirectionPolicy.
