Class BindableASTTransformation
java.lang.Object
groovy.beans.BindableASTTransformation
- All Implemented Interfaces:
- ASTTransformation,- org.objectweb.asm.Opcodes
- Direct Known Subclasses:
- VetoableASTTransformation
public class BindableASTTransformation
extends Object
implements ASTTransformation, org.objectweb.asm.Opcodes
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.

Method Details- 
hasBindableAnnotationConvenience method to see if an annotated node is@Bindable.- Parameters:
- node- the node to check
- Returns:
- true if the node is bindable
 
- 
visitHandles the bulk of the processing, mostly delegating to other methods.- Specified by:
- visitin interface- ASTTransformation
- Parameters:
- nodes- the ast nodes
- source- the source unit for the nodes
 
- 
createBindableStatementCreates a statement body similar to:this.firePropertyChange("field", field, field = value)- Parameters:
- propertyNode- the field node for the property
- fieldExpression- a field expression for setting the property value
- Returns:
- the created statement
 
- 
createSetterMethodprotected void createSetterMethod(ClassNode declaringClass, PropertyNode propertyNode, String setterName, Statement setterBlock) Creates a setter method with the given body.- Parameters:
- declaringClass- the class to which we will add the setter
- propertyNode- the field to back the setter
- setterName- the name of the setter
- setterBlock- the statement representing the setter block
 
- 
needsPropertyChangeSupportSnoops through the declaring class and all parents looking for methodsvoid addPropertyChangeListener(PropertyChangeListener),void removePropertyChangeListener(PropertyChangeListener), andvoid firePropertyChange(String, Object, Object). If any are defined all must be defined or a compilation error results.- Parameters:
- declaringClass- the class to search
- sourceUnit- the source unit, for error reporting.- @NotNull.
- Returns:
- true if property change support should be added
 
- 
addPropertyChangeSupportAdds 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()- Parameters:
- declaringClass- the class to which we add the support field and methods
