Methods

apply(List<FVariantOperation<K, E, V, D>> operations) → FVariants<K, E, V, D>
Applies a sequence of delta-based operations to this FVariants.
applyValues(List<FVariantValueDeltaOperation<K, E, V, D>> operations) → FVariants<K, E, V, D>
Applies a sequence of value-based operations to this FVariants.
call(covariant FVariants<K, E, V, D> _) → FVariants<K, E, V, D>
Applies this delta to the given value.
override
cast<T1 extends FVariantConstraint, T2 extends FVariant>() → FVariants<T1, T2, V, D>
Returns a new FVariants with the variant type parameters cast to T1 and T2.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
resolve(Set<FVariant> variants) → V
Returns most specific matching variant, or base if no constraints match.
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.

Operators

operator ==(Object other) → bool
The equality operator.
