void AssignL(CDictionaryStore& aDictStore,TUid aUid);

Description

Prepares a stream in the specified dictionary store for writing.

If no stream is associated with the specified UID, then a new stream is created and an association is made between the resulting stream id and the specified UID. If a stream is currently associated with the specified UID, then this existing stream is prepared for replacement.

Parameters

CDictionaryStore& aDictStore The dictionary store which contains the new or replacement stream. TUid aUid The UID associated with the stream.

• RWriteStream::Release()

void AssignLC(CDictionaryStore& aDictStore,TUid aUid);

Description

Prepares a stream in the specified dictionary store for writing, and places a cleanup item for this RDictionaryWriteStream object onto the cleanup stack.

If no stream is associated with the specified UID, then a new stream is created and an association is made between the resulting stream id and the specified UID. If a stream is currently associated with the specified UID, then this existing stream is prepared for replacement.

Placing a cleanup item onto the cleanup stack allows allocated resources to be cleaned up if a subsequent leave occurs.

Parameters

CDictionaryStore& aDictStore The dictionary store which contains the new or replacement stream. TUid aUid The UID associated with the stream.
