beginTask
public void beginTask(String name, int totalWork)
Notifies that the main task is beginning. This must only be called once on a given progress monitor instance.- Specified by:
beginTask
in interfaceProgressMonitor
- Parameters:
name
- the name (or description) of the main tasktotalWork
- the total number of work units into which the main task is been subdivided. If the value isUNKNOWN
the implementation is free to indicate progress in a way which doesn't require the total number of work units in advance.
-
done
public void done()
Notifies that the work is done; that is, either the main task is completed or the user canceled it. This method may be called more than once (implementations should be prepared to handle this case).- Specified by:
done
in interfaceProgressMonitor
-
internalWorked
public void internalWorked(double work)
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
- Returns:
true
if cancellation has been requested, andfalse
otherwise- See Also:
setCanceled(boolean)
-
setCanceled
public void setCanceled(boolean canceled)
Sets the cancel state to the given value.- Specified by:
setCanceled
in interfaceProgressMonitor
- Parameters:
canceled
-true
indicates that cancelation has been requested (but not necessarily acknowledged);false
clears this flag- See Also:
isCanceled()
-
setTaskName
public void setTaskName(String name)
Sets the task name to the given value. This method is used to restore the task label after a nested operation was executed. Normally there is no need for clients to call this method.- Specified by:
setTaskName
in interfaceProgressMonitor
- Parameters:
name
- the name (or description) of the main task- See Also:
beginTask(String, int)
-
setSubTaskName
public void setSubTaskName(String name)
Notifies that a subtask of the main task is beginning. Subtasks are optional; the main task might not have subtasks.- Specified by:
setSubTaskName
in interfaceProgressMonitor
- Parameters:
name
- the name (or description) of the subtask
-
worked
public void worked(int work)
Notifies that a given number of work unit of the main task has been completed. Note that this amount represents an installment, as opposed to a cumulative amount of work done to date.- Specified by:
worked
in interfaceProgressMonitor
- Parameters:
work
- the number of work units just completed
