[Groovy] Class ListenerListASTTransformation
- groovy.beans.ListenerListASTTransformation
- All Implemented Interfaces and Traits:
- ASTTransformation, org.objectweb.asm.Opcodes
@GroovyASTTransformation(phase: CompilePhase.CANONICALIZATION) @SuppressWarnings(value: ParameterCount) class ListenerListASTTransformation extends Object implements ASTTransformation, org.objectweb.asm.Opcodes
Handles generation of code for the @ListenerList
annotation.
Generally, it adds the needed add<Listener>, remove<Listener> and get<Listener>s methods to support the Java Beans API.
Additionally it adds corresponding fire<Event> methods.

Method Detail
void addAddListener(SourceUnit source, AnnotationNode node, ClassNode declaringClass, FieldNode field, ClassNode listener, String name, Object synchronize)
Adds the add<Listener> method like:
synchronized void add${name.capitalize}(${listener.name} listener) { if (listener == null) return if (${field.name} == null) ${field.name} = [] ${field.name}.add(listener) }
void addFireMethods(SourceUnit source, AnnotationNode node, ClassNode declaringClass, FieldNode field, GenericsType[] types, boolean synchronize, MethodNode method)
Adds the fire<Event> methods like:
void fire${fireMethod.capitalize()}(${parameterList.join(', ')}) { if (${field.name} != null) { def __list = new ArrayList(${field.name}) for (listener in __list) { listener.$eventMethod(${evt}) } } }
void addGetListeners(SourceUnit source, AnnotationNode node, ClassNode declaringClass, FieldNode field, ClassNode listener, String name, Object synchronize)
Adds the get<Listener>s method like:
synchronized ${name.capitalize}[] get${name.capitalize}s() { def __result = [] if (${field.name} != null) __result.addAll(${field.name}) return __result as ${name.capitalize}[] }
void addRemoveListener(SourceUnit source, AnnotationNode node, ClassNode declaringClass, FieldNode field, ClassNode listener, String name, Object synchronize)
Adds the remove<Listener> method like:
synchronized void remove${name.capitalize}(${listener.name} listener) { if (listener == null) return if (${field.name} == null) ${field.name} = [] ${field.name}.remove(listener) }
@SuppressWarnings(value: Instanceof) void visit(ASTNode[] nodes, SourceUnit source)
