Interface IComparisonSession

- All Superinterfaces:
IProgressMonitorContainer
public interface IComparisonSession extends IProgressMonitorContainer
The comparison session associated with a specific comparison process (defined by itshandle
).Comparison sessions are entities granting access to the comparison model and various high-level operations with it and with the comparison environment. Also, they allow to subscribe to model events.
Comparison sessions are managed by the
comparison manager
. It creates a session when a comparison process is started for the specifiedhandle
, and discards it either when the merge process based on that session was successfully finished, or a clientasks to stop
the session's comparison process with discarding.- See Also:
