Examples of org.eclipse.persistence.queries.InMemoryQueryIndirectionPolicy

org.eclipse.persistence.queries.InMemoryQueryIndirectionPolicy

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. @author Gordon Yorke @since TopLink/Java 3.6.3
