class stream::runs_creator< Input_, Cmp_, BlockSize_, AllocStr_ >

Forms sorted runs of data from a 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

[inline]

Returns the sorted runs object.

Returns:

Sorted runs object. The result is computed lazily, i.e. on the first call

Remarks:

Returned object is intended to be used by runs_merger object as input
