public class VetoableASTTransformation extends BindableASTTransformation
@Vetoable
annotation, and @Bindable
if also present.
Generally, it adds (if needed) a VetoableChangeSupport field and the needed add/removeVetoableChangeListener methods to support the listeners.
It also generates the setter and wires the setter through the VetoableChangeSupport.
If a Bindable
annotation is detected it also adds support similar
to what BindableASTTransformation
would do.

Modifier and Type | Method and Description |
---|---|
protected void |
addVetoableChangeSupport(ClassNode declaringClass)
Adds the necessary field and methods to support vetoable change support.
|
protected Statement |
createConstrainedStatement(PropertyNode propertyNode,
Expression fieldExpression)
Creates a statement body similar to:
this.fireVetoableChange("field", field, field = value) |
protected Statement |
createSetStatement(Expression fieldExpression)
Creates a statement body similar to:
field = value . |
protected void |
createSetterMethod(ClassNode declaringClass,
PropertyNode propertyNode,
String setterName,
Statement setterBlock)
Creates a setter method with the given body.
|
static boolean |
hasVetoableAnnotation(AnnotatedNode node)
Convenience method to see if an annotated node is
@Vetoable . |
protected boolean |
needsVetoableChangeSupport(ClassNode declaringClass,
SourceUnit sourceUnit)
Snoops through the declaring class and all parents looking for a field
of type VetoableChangeSupport.
|
void |
visit(ASTNode[] nodes,
SourceUnit source)
Handles the bulk of the processing, mostly delegating to other methods.

This differs from normal setters in that we need to add a declared exception java.beans.PropertyVetoException

Adds a new field:
"protected final java.beans.VetoableChangeSupport this$vetoableChangeSupport = new java.beans.VetoableChangeSupport(this)"
Also adds support methods:
public void addVetoableChangeListener(java.beans.VetoableChangeListener)
public void addVetoableChangeListener(String, java.beans.VetoableChangeListener)
public void removeVetoableChangeListener(java.beans.VetoableChangeListener)
public void removeVetoableChangeListener(String, java.beans.VetoableChangeListener)
