| All Members | Constructors | Methods | |||
| Member | Description | |
|---|---|---|
 | VariantVisitorBase<(Of <(<'TResult, TCandidate>)>)>(CompositeVisitor<(Of <<'(TResult>)>>)) |
Initializes a new instance of the VariantVisitorBase<(Of <(<'TResult, TCandidate>)>)> class.
|
| AsVisitor<(Of <<'(TExpression>)>>)(TExpression) |
Returns the current instance if and only if it's able to visit target,
nullNothingnullptr otherwise.
It should be overridden whenever the type of target is not enough
to choose whether the current instance can visit it or not.
(Overrides CompositeVisitor<(Of <(<'TResult>)>)>..::..VisitorBase.AsVisitor<(Of <<'(TExpression>)>>)(TExpression).) |
| VisitDowncastingVariant<(Of <<'(FromCandidate, ToCandidate>)>>)(Variant<(Of <<'(FromCandidate, ToCandidate>)>>), IVisitContext) |
Visits a downcasting Variant<(Of <(<'FromCandidate, ToCandidate>)>)>.
|
| VisitUpcastingVariant<(Of <<'(FromCandidate, ToCandidate>)>>)(Variant<(Of <<'(FromCandidate, ToCandidate>)>>), IVisitContext) |
Visits an upcasting Variant<(Of <(<'FromCandidate, ToCandidate>)>)>.
