Applied when the expression is false.

final

hashCode → int

The hash code for this object.

no setter, inherited

isCascadingToChildren → bool

Whether applying this affects the targets' descendants.

no setter, override

originalContext → TreeReference

The bind's reference, as declared.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

targets → Set<TreeReference>

The nodes this triggerable sets.

no setter, inherited

triggers → Set<TreeReference>

The references this triggerable depends on.

no setter, inherited

trueAction → ConditionAction

Applied when the expression is true.

final

Methods

addTarget(TreeReference target) → void

Adds a node this triggerable sets.

inherited

apply(FormInstance instance, EvaluationContext parentContext, TreeReference context) → List<(TreeReference, Object)>

Evaluates in context (a concrete instance of originalContext) and applies the result to every matching target; returns the affected references with the result.

inherited

applyResult(TreeReference ref, Object result, FormInstance instance) → void

Applies result to the node at ref.

override

eval(FormInstance instance, EvaluationContext ec) → Object

Evaluates the expression.

override

intersectContextWith(Triggerable other) → void

Narrows the context to what this and other have in common.

inherited

matches(Triggerable other) → bool

Whether other is the same kind of triggerable with an equal expression and the same triggers (contexts and targets are ignored).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
