Package org.geotools.event Description

Allows for events on GeoTools nested data structures.

Several of the GeoTools objects are produced in reference to specifications, in particular XML based specifications. Often we try and match the same abstractions present in a specification like SLD or Filter. But rather then make use of pure Java Beans, and make user interface code responsible for managing a host of listeners we are providing a single set of listeners located at the object matching the document base.
