public interface ReadOnlyRelationship
extends JpaContextNode

A relationship contains the settings describing how entities are related in a RelationshipMapping or AssociationOverride:

• join column
• join table
• "mapped by"
• primary key join column

Supported mappings:

• 1:1
• 1:m
• m:1
• m:m

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

STRATEGY_PROPERTY String associated with changes to the predominant strategy property

Method Summary

Entity	getEntity() Return the entity that contains the relationship's mapping or override.
RelationshipMapping	getMapping() Return the relationship's mapping; which for a mapping relationship is the relationship's parent, but in the case of an override is the overridden mapping (from a superclass or embeddable type).
ReadOnlyRelationshipStrategy	getStrategy() Return the current strategy, this is never null.
TypeMapping	getTypeMapping() Return the type mapping that contains the relationship's mapping or override.
void	initializeOn(Relationship newRelationship)
boolean	isVirtual() Return whether the the relationship is virtual.

Method Detail

getMapping

RelationshipMapping getMapping()

Return the relationship's mapping; which for a mapping relationship is the relationship's parent, but in the case of an override is the overridden mapping (from a superclass or embeddable type).

getTypeMapping

TypeMapping getTypeMapping()

Return the type mapping that contains the relationship's mapping or override.

getEntity

Entity getEntity()

Return the entity that contains the relationship's mapping or override. This is just a convenience method that calls getTypeMapping() and returns null if the result is not an Entity.

getStrategy

ReadOnlyRelationshipStrategy getStrategy()

Return the current strategy, this is never null.

isVirtual

boolean isVirtual()

Return whether the the relationship is virtual.

initializeOn

void initializeOn(Relationship newRelationship)
