Constructs an uninitialised object. It is necessary because there are also non-default constructors in this class.
inline RStoreWriteStream(const MExternalizer< TStreamRef > &anExter);
Constructs an object with an externaliser. The store map CStoreMap is an example of an externalizer.

IMPORT_C TStreamId CreateL(CStreamStore &aStore);
Creates a new stream.
The function creates a new stream in the specified store and prepares the stream for writing. The function returns the new stream id, and leaves if it cannot complete successfully.
Note that a call to this function must be matched by a call to RWriteStream::CommitL() before this object is disposed of.

Creates a new stream, putting a cleanup item onto the cleanup stack.
The function creates a new stream in the specified store and prepares the stream for writing. The function returns the new stream id, and leaves if it cannot complete successfully.
Putting a cleanup item onto the cleanup stack allows allocated resources to be cleaned up if a subsequent leave occurs.
Note that a call to this function must be matched by a call to RWriteStream::CommitL() before this object is disposed of.

Opens an existing stream and prepares it for overwriting.
The function leaves if cannot complete successfully.
