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.

Method Detail

isOwner

boolean isOwner()

Return whether the relationship's mapping is the relationship owner.

See Also:

AttributeMapping.isRelationshipOwner()

isOwnedBy

boolean isOwnedBy(RelationshipMapping mapping)

Return whether the specified mapping owns the relationship.

See Also:

AttributeMapping.isOwnedBy(AttributeMapping)

isTargetForeignKey

boolean isTargetForeignKey()

Return whether the relationship's mapping is a target foreign key relationship. A one-to-many mapping with a join column will have the foreign key in the target table.

isOverridable

boolean isOverridable()

Return whether the relationship's mapping can be overridden with an association override.
