Ref Element

Group membership: Property & method calls

References an existing object from the builder's context. It is possible to view ID attributes as meaning variable names. In this case, ref acts as the right-hand side of expressions. Instantiation would then be the left-hand side of expressions.

The references' value is dropped onto the builder's stack, ready for consumption by a parent methodCall, return or property.
