Detailed Description

template<class TRange, class TValue, class Overlap, class Less = std::less<TRange>>
class cgatools::util::RangeIntersector< TRange, TValue, Overlap, Less >

Class that maintains a mapping from key -> value, where the key is a type with range semantics, for the purpose of finding the intersection of a range to a set of ranges.

The class requires the key have an overlap operator defined, and a less than operator defined, such that:

• The less operator satisfies the usual requirements for a less-than operator (defines a strict total order).
• If !(a<b) and !(b<a), then overlap(a,b).
• If a<b, b<c, overlap(a,m), and overlap(c,m), then overlap(b,m).
• overlap(a,m) iff overlap(m,a).

const [inline]

Debugging function to find out how many trees were required for this RangeIntersector.

Generally, the more trees, the more expensive lookups are.

template<class TRange, class TValue, class Overlap, class Less = std::less<TRange>>

void cgatools::util::RangeIntersector< TRange, TValue, Overlap, Less >::intersect	(	const TRange &	range,
		std::vector< typename MapType::const_iterator > &	result
	)			const [inline]

Find the intersection of the given range with all the ranges in the set.

template<class TRange, class TValue, class Overlap, class Less = std::less<TRange>>

bool cgatools::util::RangeIntersector< TRange, TValue, Overlap, Less >::intersects

(

const TRange &

range

)

const [inline]

Returns true iff the given range intersects the set of ranges in this RangeIntersector.
