Detailed Description

template<class ValueType_, class Cmp_, unsigned BlockSize_, class AllocStr_>
class stream::runs_creator< from_sorted_sequences< ValueType_ >, Cmp_, BlockSize_, AllocStr_ >

Forms sorted runs of data taking elements in sorted order (element by element).

A specialization of runs_creator that allows to create sorted runs data structure usable for runs_merger from sequences of elements in sorted order.
Template parameters:

• ValueType_ type of values (parameter for from_sorted_sequences strategy)
• 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

stream::runs_creator< from_sorted_sequences< ValueType_ >, Cmp_, BlockSize_, AllocStr_ >::runs_creator	(	Cmp_	c,
		unsigned_type	memory_to_use
	)			[inline]

Creates the object.

Parameters:

	c	comparator object
	memory_to_use	memory amount that is allowed to used by the sorter in bytes. Recommended value: 2 * block_size * D
