Methods

Visit(SyntaxNode)

Called when the walker visits a node. This method may be overridden if subclasses want to handle the node. Overrides should call back into this base method if they want the children of this node to be visited.

Declaration

public virtual void Visit(SyntaxNode node)

Parameters

Type	Name	Description
SyntaxNode	node	The current node that the walker is visiting.

VisitToken(SyntaxToken)

Called when the walker visits a token. This method may be overridden if subclasses want to handle the token. Overrides should call back into this base method if they want the trivia of this token to be visited.

Declaration

protected virtual void VisitToken(SyntaxToken token)

Parameters

Type	Name	Description
SyntaxToken	token	The current token that the walker is visiting.

VisitTrivia(SyntaxTrivia)

Called when the walker visits a trivia syntax. This method may be overridden if subclasses want to handle the token. Overrides should call back into this base method if they want the children of this trivia syntax to be visited.

Declaration

protected virtual void VisitTrivia(SyntaxTrivia trivia)

Parameters

Type	Name	Description
SyntaxTrivia	trivia	The current trivia syntax that the walker is visiting.
