hashCode → int

Hash of toString, as in JavaRosa.

no setter, inherited

override

evalIn(EvaluationContext context) → Object

Evaluates against context's main instance.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pivot(DataInstance? model, EvaluationContext context, List<Object> pivots, Object sentinel) → Object?

Pivots this expression around sentinel (the validated node's reference), adding CmpPivots to pivots.

inherited

toString() → String

A string representation of this object.

inherited

Operators
