Detailed Description

template<class Input_, class Cmp_, unsigned BlockSize_ = STXXL_DEFAULT_BLOCK_SIZE(typename Input_::value_type), class AllocStr_ = STXXL_DEFAULT_ALLOC_STRATEGY>
class stream::sort< Input_, Cmp_, BlockSize_, AllocStr_ >

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 .
