Sets or resets this listener to determinate mode using the specified message, minimum and maximum values.

Specified by:

init in interface ProgressListener

update

public void update(int progress)

Description copied from interface: ProgressListener

Updates the progress to the specified value. Implementations may rely on this happening in order to provide advanced progress information, therefore the caller should update continously and not "jump"around.

Specified by:

update in interface ProgressListener

Parameters:

progress - the new progress value

label

public void label(java.lang.String label)

Description copied from interface: ProgressListener

Labels the current task with the specified string.

Specified by:

label in interface ProgressListener

Parameters:

label - a label describing the current task

finish

public void finish()

Description copied from interface: ProgressListener

Finishes the display of progress by a progress listener, e.g. by closing a progress dialog.

Specified by:

finish in interface ProgressListener

iterator

public java.util.Iterator<ProgressListener> iterator()

Returns and Iterator over all ProgressListeners registered with this manager.

Specified by:

iterator in interface java.lang.Iterable

getProgress

public int getProgress()

Returns the progress from the first registered listeners.

Specified by:

getProgress in interface ProgressListener

Returns:

the current progress value

size

public int size()

Returns the number of ProgressListener registered with this manager.

Returns:

the number of ProgressListener in this manager.
