public class ObservableList extends Object
List decorator that will trigger PropertyChangeEvents when a value changes.
An optional Closure may be specified and will work as a filter, if it returns true the property
will trigger an event (if the value indeed changed), otherwise it won't. The Closure may receive
1 or 2 parameters, the single one being the value, the other one both the key and value, for
example:
// skip all properties whose value is a closure def map = new ObservableList( {!(it instanceof Closure)} ) // skip all properties whose name matches a regex def map = new ObservableList( { name, value -> !(name =˜ /[A-Z+]/) } )The current implementation will trigger specialized events in the following scenarios, you need not register a different listener as those events extend from PropertyChangeEvent
