java.lang.Object
  fmpp.progresslisteners.StatisticsProgressListener

All Implemented Interfaces:

ProgressListener

public class StatisticsProgressListener
extends java.lang.Object
implements ProgressListener

Spins some counters regarding the work of the Engine. All methods of this listener can be called from multiple threads. The current state of counters can be read while the engine is working.

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 occured.

event - The code of the envent: 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.
