public interface JoinTableRelationship
extends Relationship

Join table relationship

• 1:1 (JPA 2.0)
• 1:m
• m:1 (JPA 2.0)
• m:m
• association override (JPA 2.0)

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 Summary

JoinTableRelationshipStrategy	getJoinTableStrategy() Return the (never null) strategy used to configure the relationship's join table strategy.
boolean	mayHaveDefaultJoinTable() Return whether this relationship may potentially have a default join table.
boolean	strategyIsJoinTable() Return whether the join table strategy is the relationship's current strategy.

Method Detail

getJoinTableStrategy

JoinTableRelationshipStrategy getJoinTableStrategy()

Return the (never null) strategy used to configure the relationship's join table strategy.

strategyIsJoinTable

boolean strategyIsJoinTable()

Return whether the join table strategy is the relationship's current strategy.

mayHaveDefaultJoinTable

boolean mayHaveDefaultJoinTable()

Return whether this relationship may potentially have a default join table. For example, a M-M mapping may have a default join table if it does not specify a "mapped by" attribute or a join table; but a M-1 mapping does not support a default join table in any situation.
