Methods

method CopyFromAndSave(source As %AbstractStream) as %Status
Inherited description: Copy the stream from source into the current stream ignoring anything already in the current stream and save the result to the permanent location. This is used to optimise the copying of say a %GlobalCharacterStream to another %GlobalCharacterStream to avoid copying into temporary storage first and then moving this to the permanent storage when SaveStream() is called.

Note that any locking or transaction handling must be done by the caller.
