Adds the necessary field and methods to support property change support.
Adds a new field:
protected final java.beans.PropertyChangeSupport this$PropertyChangeSupport = new java.beans.PropertyChangeSupport(this)"
Also adds support methods:
public void addPropertyChangeListener(java.beans.PropertyChangeListener)public void addPropertyChangeListener(String, java.beans.PropertyChangeListener)public void removePropertyChangeListener(java.beans.PropertyChangeListener)public void removePropertyChangeListener(String, java.beans.PropertyChangeListener)public java.beans.PropertyChangeListener[] getPropertyChangeListeners()
declaringClass - the class to which we add the support field and methods Creates a statement body similar to:
this.firePropertyChange("field", field, field = value)
propertyNode - the field node for the propertyfieldExpression - a field expression for setting the property valueCreates a setter method with the given body.
declaringClass - the class to which we will add the setterpropertyNode - the field to back the settersetterName - the name of the settersetterBlock - the statement representing the setter block Convenience method to see if an annotated node is @Bindable.
node - the node to check Snoops through the declaring class and all parents looking for methods
void addPropertyChangeListener(PropertyChangeListener),
void removePropertyChangeListener(PropertyChangeListener), and
void firePropertyChange(String, Object, Object). If any are defined all
must be defined or a compilation error results.
declaringClass - the class to searchsourceUnit - the source unit, for error reporting. @NotNull.Handles the bulk of the processing, mostly delegating to other methods.
nodes - the ast nodessource - the source unit for the nodes
