| org.geotools.event.GTEvent
All known Subclasses: org.geotools.event.GTEventImpl,
| GTEvent | | public interface GTEvent (Code) | | Captures changes to Style.
The "delta" acts as a series of bread crumbs allowing you the listener to
figure out what changed where. The Type answers that other peskey
question: when.
You should be warned that deltas may also be "saved up" for a rainy day,
this keeps user interfaces from being flooded with a cascade of events. The
best example is a "macro" that makes a series of changes and only reports
back a compound change resulting from the batch opperation.
