Detailed Description

This class interacts with the EventEngine to simulate real-time input events. The events can be loaded from disk (XML files), and can be either batched or realtime events. Alternatively, events generated by an actual pen can be saved out to a file, for future replay.

PenEvent createEventFromString

(

String

eventString

)

The inverse of createStringFromEvent(.

..). This creates a PenEvent object from one line of the eventData file.

Parameters:

eventString

Returns:

void loadEventDataFrom

(

File

eventDataFile

)

Parameters:

eventDataFile

void loadMostRecentEventData

(

)

Load the most recent event data file.

void replay

(

final List< PenEvent >

events

)

Replays the list of events.

.. Ideally, this should play it back at real time or some multiple of realtime...

Threaded, because we do not want any GUI to block when calling this. Alternatively, refactor this into blocking & nonblocking versions.

Parameters:

events

void replayLoadedEvents

(

)

Replay the events that have been loaded, in the order that they appear in the list.

void saveEvent

(

PenEvent

event

)

Save this pen event.

This is done automatically for events streamed through the Event Engine. In the future, we should probably log at the PenListener level too! This allows arbitrary event data save and replay.

Parameters:

event
