Examples of ContainerPolicy

oracle.toplink.essentials.internal.queryframework.ContainerPolicy

Purpose: Used to support collections in read queries.

Responsibilities: Map the results into the appropriate collection instance. Generically support special collections like cursored stream and virtual collection. @author James Sutherland @since TOPLink/Java 1.2
