Hash of toString, as in JavaRosa.

no setter, inherited

Methods

containsFunc(String name) → bool

Whether this expression calls the function named name anywhere.

override

eval(DataInstance? model, EvaluationContext context) → Object

JavaRosa returns null for an undefined variable, which later fails in a type conversion; DartRosa reports it directly (see DEVIATIONS.md).

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.

override

Operators

operator ==(Object other) → bool

Structural equality, matching JavaRosa's equals.
