allocator	to use for allocating and deallocating memory

Member Function Documentation

compute()

CompactSketch compute	(	FwdSketch &&	a,
		const Sketch &	b,
		bool	ordered = true
	)		const

Computes the A-not-B set operation given two sketches.

Parameters

a	sketch A
b	sketch B
ordered	optional flag to specify if an ordered sketch should be produced

Returns

the result of A-not-B as a compact sketch
