Interface TwingNodeVisitor

The interface that all node visitors must implement.

interface TwingNodeVisitor {
enterNode(node: TwingBaseNode<any, TwingBaseNodeAttributes, TwingBaseNodeChildren>, source: TwingSource): TwingBaseNode<any, TwingBaseNodeAttributes, TwingBaseNodeChildren>;
leaveNode(node: TwingBaseNode<any, TwingBaseNodeAttributes, TwingBaseNodeChildren>, source: TwingSource): null | TwingBaseNode<any, TwingBaseNodeAttributes, TwingBaseNodeChildren>;
}
