Class RShareWriteStream

class RShareWriteStream : public RWriteStream;

Description

Supports the opening, for writing, of a stream which shares its host with other streams.

This is also called a shared write stream.

The class uses a RShareBuf stream buffer.

inline RShareWriteStream();

Description

Constructs an empty shared write stream object.

Call RShareWriteStream::Open(TStreamExchange &,TStreamPos) to prepare the shared stream for writing.

• RShareWriteStream::Open(TStreamExchange &,TStreamPos)Prepares the shared stream for writing.

inline RShareWriteStream(const MExternalizer< TStreamRef > &anExter);

Description

Parameters

const MExternalizer< TStreamRef > &anExter

IMPORT_C RShareWriteStream(TStreamExchange &aHost, TStreamPos aPos=KStreamBeginning);

Description

Constructs the shared write stream object and prepares the shared stream for writing.

Parameters

TStreamExchange &aHost The object that manages shared streaming. TStreamPos aPos The position of the stream within the host stream. Defaults to the beginning of the host stream, if not explicitly specified.

IMPORT_C void Open(TStreamExchange &aHost, TStreamPos aPos=KStreamBeginning);

Description

Prepares the shared stream for writing.

Parameters

TStreamExchange &aHost The object that manages shared streaming. TStreamPos aPos The position of the stream within the host stream. Defaults to the beginning of the host stream, if not explicitly specified.
