Detailed Description

template<class Input_, class Cmp_, unsigned BlockSize_ = (2 * 1024 * 1024), class AllocStr_ = stxxl::RC, class runs_creator_type = runs_creator<Input_, Cmp_, BlockSize_, AllocStr_>>
class stream::sort< Input_, Cmp_, BlockSize_, AllocStr_, runs_creator_type >

Produces sorted stream from input stream.

Template Parameters:

	Input_	type of the input stream
	Cmp_	type of comparison object used for sorting the runs
	BlockSize_	size of blocks used to store the runs
	AllocStr_	functor that defines allocation strategy for the runs

Remarks:

Implemented as the composition of runs_creator and runs_merger .
