Detailed Description

Input buffer for a blob using an istream.

This class is the BlobIBuffer that makes use of an istream object. The istream can be any type (ifstream, istringstream, ...). It can, for instance, be used to read from a file or a socket.

Constructor & Destructor Documentation

BlobIBufStream()

dp3::blob::BlobIBufStream::BlobIBufStream ( std::istream &  )

explicit

Construct it with the underlying istream object.

~BlobIBufStream()

virtual dp3::blob::BlobIBufStream::~BlobIBufStream ( )

virtual

Destructor.

Member Function Documentation

get()

virtual uint64_t dp3::blob::BlobIBufStream::get ( void *  buffer, uint64_t  nbytes  )

virtual

Get the requested nr of bytes.

Implements dp3::blob::BlobIBuffer.

setPos()

virtual int64_t dp3::blob::BlobIBufStream::setPos ( int64_t  pos )

virtual

Set the position in the stream. It returns the new position which is -1 if the stream is not seekable.

Implements dp3::blob::BlobIBuffer.

tellPos()

virtual int64_t dp3::blob::BlobIBufStream::tellPos ( ) const

virtual

Get the position in the stream. -1 is returned if the stream is not seekable.

Implements dp3::blob::BlobIBuffer.
