示例1: acceptForeignKey

}

}示例2: _addForeignKeyConstraint

* @param ForeignKeyConstraint $constraint
*/

// add an explicit index on the foreign key columns. If there is already an index that fullfils this requirements drop the request.
// In the case of __construct calling this method during hydration from schema-details all the explicitly added indexes
// lead to duplicates. This creates compuation overhead in this case, however no duplicate indexes are ever added (based on columns).
