@GroovyASTTransformation(phase= CompilePhase.CANONICALIZATION) public class BindableASTTransformation extends Object
Handles generation of code for the @Bindable annotation when @Vetoable
is not present.
Generally, it adds (if needed) a PropertyChangeSupport field and the needed add/removePropertyChangeListener methods to support the listeners.
It also generates the setter and wires the setter through the PropertyChangeSupport.
If a Vetoable annotation is detected it does nothing and lets the VetoableASTTransformation handle all the changes.

needsPropertyChangeSupport(ClassNode declaringClass, org.codehaus.groovy.control.SourceUnit sourceUnit)Snoops through the declaring class and all parents looking for methods void addPropertyChangeListener(PropertyChangeListener),

visit(ASTNode[] nodes, org.codehaus.groovy.control.SourceUnit source)Handles the bulk of the processing, mostly delegating to other methods. |
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
