Join column relationship

• 1:1
• 1:m
• m:1
• association override

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

getJoinColumnStrategy

ReadOnlyJoinColumnRelationshipStrategy getJoinColumnStrategy()

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

strategyIsJoinColumn

boolean strategyIsJoinColumn()

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

mayHaveDefaultJoinColumn

boolean mayHaveDefaultJoinColumn()

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