Class BindableASTTransformation

BindableASTTransformation

BindableASTTransformation()

addListenerToClass

void addListenerToClass(SourceUnit source, AnnotationNode node, ClassNode classNode)

addListenerToProperty

void addListenerToProperty(SourceUnit source, AnnotationNode node, ClassNode declaringClass, FieldNode field)

addPropertyChangeSupport

void addPropertyChangeSupport(ClassNode declaringClass)

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()

param:

declaringClass the class to which we add the support field and methods

createBindableStatement

Statement createBindableStatement(PropertyNode propertyNode, Expression fieldExpression)

Creates a statement body similar to: pcsField.firePropertyChange("field", field, field = value)

param:

propertyNode the field node for the property

param:

fieldExpression a field expression for setting the property value

return:

the created statement

createListenerSetter

void createListenerSetter(SourceUnit source, AnnotationNode node, ClassNode classNode, PropertyNode propertyNode)

createSetterMethod

void createSetterMethod(ClassNode declaringClass, PropertyNode propertyNode, String setterName, Statement setterBlock)

Creates a setter method with the given body.

param:

declaringClass the class to which we will add the setter

param:

propertyNode the field to back the setter

param:

setterName the name of the setter

param:

setterBlock the statement representing the setter block

hasBindableAnnotation

public static boolean hasBindableAnnotation(AnnotatedNode node)

The found or created PropertyChangeSupport field

needsPropertyChangeSupport

boolean needsPropertyChangeSupport(ClassNode declaringClass)

Snoops through the declaring class and all parents looking for a field of type PropertyChangeSupport. Remembers the field and returns false if found otherwise returns true to indicate that such support should be added.

param:

declaringClass the class to search

return:

true if property change support should be added

visit

public void visit(def nodes, SourceUnit source)

Handles the bulk of the processing, mostly delegating to other methods.

param:

nodes the ast nodes

param:

source the source unit for the nodes
