JoinObject

abstract class JoinObject extends StandardObject

The base class for join objects managed by an ObjectJoin field type.

Includes utility functions for creating/loading/deleting join objects. A class that extends this one to join two classes together in a many-to-many needs (at a minimum) to have two fields, each as an ObjectRefs to a class.

Constants

IDLength

The length of the ID used to identify the object
