Detailed Description

class Query_terms< visit_order, visit_leaves >::Query_term_iterator

The iterator class itself is private.

Only used directly by begin and end

Constructor & Destructor Documentation

Query_term_iterator() [1/2]

template<Visit_order visit_order, Visit_leaves visit_leaves>

Query_terms< visit_order, visit_leaves >::Query_term_iterator::Query_term_iterator ( Query_term *  root )

inline

Construct an iterator over the query term tree rooted in root, optionally skipping the leaves.

Skipping is useful for those cases where the leaves are visited separately[1] and we only want to visit the set operation nodes in the tree. [1] By walking the Query_expression::first_query_block and Query_block::next_query_block chain

Parameters

root	the node to start iteration from
