## groovy.util
Class ObservableMap

    java.lang.Object
      groovy.util.ObservableMap

All Implemented Interfaces:
  Map

    public class ObservableMap

extends Object
implements Map

Map 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 ObservableMap( {!(it instanceof Closure)} )

     // skip all properties whose name matches a regex
     def map = new ObservableMap( { name, value -> !(name =~ /[A-Z+]/) } )
