Method Details

notifyProgressEvent

public void notifyProgressEvent(Engine engine,
 int event,
 File src,
 int pMode,
 Throwable error,
 Object param)

Description copied from interface: ProgressListener

Method called be the engine to notify events.

It is guaranteed that this method will not be called concurrently as far as the listener is added to a single Engine instance only.

Specified by:

notifyProgressEvent in interface ProgressListener

Parameters:

engine - The engine instance where the event has occurred.

event - The code of the event: an EVENT_... constant. As new event types can be introduced with new FMPP versions (even if it happens very seldom), a progress listener implementation should survive events that it does not understand. That is, it must not stop with an error, but it should silently ignore the event.

src - Depending on event the source file or null.

pMode - Depending on event the proccessing mode (Engine.PMODE_... constant) or Engine.PMODE_NONE. Note that new processing modes may be added as FMPP evolvers, so values that are not known be the progress listener should be handler nicely, and never cause error.

error - The error, or null if there was no error.

param - Extra information about the event. The class and meaning of object depends on the concrete event:

• For EVENT_WARNING it is a String that describles the reason of warning.

public PrintWriter getPrintWriter()

close
