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_>

buf_ostream< BlkTp_, BIDIteratorTp_ >::buf_ostream	(	bid_iterator_type	first_bid,
		int_type	nbuffers
	)			`[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 ( ) [inline, virtual]

Deallocates internal objects.

Member Function Documentation

template<typename BlkTp_, typename BIDIteratorTp_>

reference buf_ostream< BlkTp_, BIDIteratorTp_ >::current ( ) [inline]

Returns reference to the current record.

Returns:: reference to the current record

template<typename BlkTp_, typename BIDIteratorTp_>

reference buf_ostream< BlkTp_, BIDIteratorTp_ >::operator* ( ) [inline]

Returns reference to the current record.

Returns:: reference to the current record

template<typename BlkTp_, typename BIDIteratorTp_>

_Self& buf_ostream< BlkTp_, BIDIteratorTp_ >::operator++ ( ) [inline]

Moves to the next record in the stream.

Returns:: reference to itself after the advance

template<typename BlkTp_, typename BIDIteratorTp_>

_Self& buf_ostream< BlkTp_, BIDIteratorTp_ >::operator<< ( const_reference record ) [inline]

Output stream operator, writes out record.

Parameters:

record

const reference to block record type, containing a value of record to write to the stream

Returns:: reference to itself (stream object)
