Function Documentation

dispatch() [1/2]

template<typename Visitor >

void hilti::visitor::dispatch	(	Visitor &&	visitor,
		Node *	n
	)

Dispatches a visitor for a single node.

dispatch() [2/2]

template<typename Visitor , typename ResultFunc >

auto hilti::visitor::dispatch	(	Visitor &&	visitor,
		Node *	node,
		ResultFunc	result
	)

Dispatches a visitor for a single node, then runs a callback and returns its result.

range()

template<typename Visitor , typename Node >

auto hilti::visitor::range	(	Visitor &&	visitor,
		Node *	root,
		std::string_view	limit_to_tag = {}
	)

Return a range that iterates over AST, returning each node successively.

visit() [1/2]

template<typename Visitor , typename Node , typename ResultFunc >

auto hilti::visitor::visit	(	Visitor &&	visitor,
		Node *	root,
		std::string_view	limit_to_tag,
		ResultFunc	result
	)

Walks the AST recursively and calls dispatch for each node, then runs callback and returns its result.

visit() [2/2]

template<typename Visitor , typename Node >

auto hilti::visitor::visit	(	Visitor &&	visitor,
		Node *	root,
		std::string_view	limit_to_tag = {}
	)

Walks the AST recursively and calls dispatch for each node.
