public class BindableASTTransformation extends Object implements ASTTransformation, org.objectweb.asm.Opcodes
@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.

Modifier and Type | Method and Description |
---|---|
protected void |
addPropertyChangeSupport(ClassNode declaringClass)
Adds the necessary field and methods to support property change support.
|
protected Statement |
createBindableStatement(PropertyNode propertyNode,
Expression fieldExpression)
Creates a statement body similar to:
this.firePropertyChange("field", field, field = value) |
protected void |
createSetterMethod(ClassNode declaringClass,
PropertyNode propertyNode,
String setterName,
Statement setterBlock)
Creates a setter method with the given body.
|
static boolean |
hasBindableAnnotation(AnnotatedNode node)
Convenience method to see if an annotated node is
@Bindable . |
protected boolean |
needsPropertyChangeSupport(ClassNode declaringClass,
SourceUnit sourceUnit)
Snoops through the declaring class and all parents looking for methods
void addPropertyChangeListener(PropertyChangeListener) ,
void removePropertyChangeListener(PropertyChangeListener) , and
void firePropertyChange(String, Object, Object) . |
void |
visit(ASTNode[] nodes,
SourceUnit source)
Handles the bulk of the processing, mostly delegating to other methods.

Adds a new field:

"
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)
