Internal method to handle scaling correctly. This method must not be called by a client. Clients should always use the methodworked(int)
.- Specified by:
internalWorked
in interfaceProgressMonitor
- Parameters:
work
- the amount of work done
-
isCanceled
public boolean isCanceled()
Returns whether cancelation of current operation has been requested. Long-running operations should poll to see if cancelation has been requested.- Specified by:
isCanceled
in interfaceProgressMonitor
