Class MapChangeListenerASTTransformation

java.lang.Object

org.codehaus.griffon.compile.core.ast.transform.AbstractASTTransformation

org.codehaus.griffon.compile.core.ast.transform.MapChangeListenerASTTransformation

All Implemented Interfaces:

org.codehaus.groovy.transform.ASTTransformation

public class MapChangeListenerASTTransformation
extends AbstractASTTransformation

Handles generation of code for the @MapChangeListener annotation.

Any closures found as the annotation's value will be either transformed into inner classes that implement MapChangeListener (when the value is a closure defined in place) or be casted as a proxy of MapChangeListener (when the value is a property reference found in the same class).

List of closures are also supported.

Since:

2.4.0

Method Detail

hasListenerAnnotation

public static boolean hasListenerAnnotation(org.codehaus.groovy.ast.AnnotatedNode node)

Convenience method to see if an annotated node is @MapChangeListener.

Parameters:

node - the node to check

Returns:

true if the node is an event publisher

addListenerToProperty

public static void addListenerToProperty(org.codehaus.groovy.control.SourceUnit source,
                                         org.codehaus.groovy.ast.AnnotationNode annotation,

                                         org.codehaus.groovy.ast.FieldNode field)

visit

public void visit(org.codehaus.groovy.ast.ASTNode[] nodes,
                  org.codehaus.groovy.control.SourceUnit source)

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

Parameters:

nodes - the ast nodes

source - the source unit for the nodes
