## Annotation Type Bindable

-     @Documented
      @Retention(SOURCE)
      @Target({FIELD,TYPE})
      public @interface Bindable

  Annotates a groovy property or a class. When annotating a property it indicates that the property should be a bound property according to the JavaBeans spec, announcing to listeners that the value has changed.

  When annotating a class it indicates that all groovy properties in that class should be bound as though each property had the annotation (even if it already has it explicitly).

  It is a compilation error to place this annotation on a field (that is not a property, i.e. has scope visibility modifiers).

  If a property with a user defined setter method is annotated the code block is wrapped with the needed code to fire off the event.

  The following example shows how you can use this annotation on fields of a class:

       class Person {
          @groovy.beans.Bindable
          String firstName

          @groovy.beans.Bindable
          def zipCode
       }

  The above example will generate code that is similar to the next snippet. Notice the difference between a String property and a def/Object property:

       public class Person {
           @groovy.beans.Bindable
           private java.lang.String firstName
           @groovy.beans.Bindable
           private java.lang.Object zipCode
           final private java.beans.PropertyChangeSupport this$propertyChangeSupport

           public Person() {
               this$propertyChangeSupport = new java.beans.PropertyChangeSupport(this)
           }

           public void addPropertyChangeListener(java.beans.PropertyChangeListener listener) {
               this$propertyChangeSupport.addPropertyChangeListener(listener)
           }

           public void addPropertyChangeListener(java.lang.String name, java.beans.PropertyChangeListener listener) {
               this$propertyChangeSupport.addPropertyChangeListener(name, listener)
           }

           public void removePropertyChangeListener(java.beans.PropertyChangeListener listener) {
               this$propertyChangeSupport.removePropertyChangeListener(listener)
           }

           public void removePropertyChangeListener(java.lang.String name, java.beans.PropertyChangeListener listener) {
               this$propertyChangeSupport.removePropertyChangeListener(name, listener)
           }

           public void firePropertyChange(java.lang.String name, java.lang.Object oldValue, java.lang.Object newValue) {
               this$propertyChangeSupport.firePropertyChange(name, oldValue, newValue)
           }

           public java.beans.PropertyChangeListener[] getPropertyChangeListeners() {
               return this$propertyChangeSupport.getPropertyChangeListeners()
           }

           public java.beans.PropertyChangeListener[] getPropertyChangeListeners(java.lang.String name) {
               return this$propertyChangeSupport.getPropertyChangeListeners(name)
           }

           public void setFirstName(java.lang.String value) {
               this.firePropertyChange('firstName', firstName, firstName = value )
           }

           public void setZipCode(java.lang.Object value) {
               this.firePropertyChange('zipCode', zipCode, zipCode = value )
           }
       }
