l.s.x.m.XRef(StormBase) : class documentation

Cross-reference between two objects.

For references to local objects (there is currently no other kind), another reference in the opposite direction exists.

The to_id_int and from_id_int columns exist for efficient SQL joins. They are set automatically when the ID looks like an integer.

NOTE: This should rarely be used directly. Prefer IXRefSet unless porting an old query.

Inherited from StormBase:

Method
