Classes
class	Explorer
	Interface: strategy for exploring the structure. More...
class	ChildExplorer
	Strategy: explore the structure just by following the given iterator; usually this yields an element's children. More...
class	DeepExplorer
	Strategy: explore the structure depth first. More...
class	UpExplorer
	Strategy: explore the structure upwards, ascending until reaching the root element. More...
class	ResultSet
	on query, an individual result set is prepared to be explored by the invoking client code. More...
struct	UseThisIndex

Functions
bool	acceptAllObjects_ (Pla)
template<typename QUERY >
ContentFilter	getContentFilter (QUERY const &query)
	use filter predicate provided by the concrete query
ContentFilter	getContentFilter (ScopeQuery< MObject > const &)
	especially queries for MObjects need not be filtered
template<typename MO >
QueryID	whenQueryingFor ()
	shortcut for a suitable QueryID
