Examples of org.datanucleus.metadata.ForeignKeyMetaData

org.datanucleus.metadata.ForeignKeyMetaData
Foreign keys in metadata serve two quite different purposes. First, when generating schema, the foreign key element identifies foreign keys to be generated. Second, when using the database, foreign key elements identify foreign keys that are assumed to exist in the database. This is important for the runtime to properly order insert, update, and delete statements to avoid constraint violations. A foreign-key element can be contained by a field, element, key, value, or join element, if all of the columns mapped are to be part of the same foreign key. A foreign-key element can be contained within a class element. In this case, the column elements are mapped elsewhere, and the column elements contained in the foreign-key element have only the column name.
