EclipseLink Core 4.0.2 · 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.

Field Summary

Modifier and Type	Field and Description
protected int	policy
protected ObjectLevelReadQuery	query Used to set the policy state in the query.
public static final int	SHOULD_IGNORE_EXCEPTION_RETURN_CONFORMED If a non-instantiated indirection object is encountered the object is assumed to conform.
public static final int	SHOULD_IGNORE_EXCEPTION_RETURN_NOT_CONFORMED If a non-instantiated indirection object is encountered the object is assumed to not conform.
public static final int	SHOULD_THROW_INDIRECTION_EXCEPTION If a non-instantiated indirection object is encountered an exception is thrown.
public static final int	SHOULD_TRIGGER_INDIRECTION If a non-instantiated indirection object is encountered an exception it is instantiated.
