Detailed Description

template<typename BlkTp_, typename BIDIteratorTp_>
class buf_ostream< BlkTp_, BIDIteratorTp_ >

Buffered output stream.

Writes data records to the stream of blocks.

Remarks

Writing performed in the background, i.e. with overlapping of I/O and computation

Constructor & Destructor Documentation

template<typename BlkTp_, typename BIDIteratorTp_>

inline

Constructs output stream object.

Parameters

first_bid	bid_iterator pointing to the first block of the stream
nbuffers	number of buffers for internal use

template<typename BlkTp_, typename BIDIteratorTp_>

virtual buf_ostream< BlkTp_, BIDIteratorTp_ >::~buf_ostream ( )

inlinevirtual

Deallocates internal objects.
