| Modifier and Type | Method and Description | 
|---|---|
| void | addHandler(TypeCheckingExtension handler) | 
| void | afterMethodCall(MethodCall call)Allows the extension to perform additional tasks after the type checker actually visits a method call. | 
| void | afterVisitClass(ClassNode node)Allows the extension to perform additional tasks after the type checker actually visited a class node. | 
| void | afterVisitMethod(MethodNode node)Allows the extension to perform additional tasks after the type checker actually visited a method node. | 
| boolean | beforeMethodCall(MethodCall call)Allows the extension to perform additional tasks before the type checker actually visits a method call. | 
| boolean | beforeVisitClass(ClassNode node)Allows the extension to perform additional tasks before the type checker actually visits a class node. | 
| boolean | beforeVisitMethod(MethodNode node)Allows the extension to perform additional tasks before the type checker actually visits a method node. | 
| void | finish()Subclasses should implement this method if they need to perform additional
 checks after the type checker has finished its work. | 
| List<MethodNode> | handleAmbiguousMethods(List<MethodNode> nodes,
                      Expression origin)This method is called by the type checker before throwing an "ambiguous method" error, giving the chance
 to the extension to select the method properly. | 
| boolean | handleIncompatibleAssignment(ClassNode lhsType,
                            ClassNode rhsType,
                            Expression assignmentExpression)This method is called by the type checker when an assignment is not allowed by the type checker. | 
| boolean | handleIncompatibleReturnType(ReturnStatement returnStatement,
                            ClassNode inferredReturnType)Allows the extension to catch incompatible return types. | 
| List<MethodNode> | handleMissingMethod(ClassNode receiver,
                   String name,
                   ArgumentListExpression argumentList,
                   ClassNode[] argumentTypes,
                   MethodCall call)This method is called by the type checker when a method call cannot be resolved. | 
| boolean | handleUnresolvedAttribute(AttributeExpression aexp)This method is called by the type checker when an attribute expression cannot
 be resolved (for example, when an attribute doesn't exist). | 
| boolean | handleUnresolvedProperty(PropertyExpression pexp)This method is called by the type checker when a property expression cannot
 be resolved (for example, when a property doesn't exist). | 
| boolean | handleUnresolvedVariableExpression(VariableExpression vexp)This method is called by the type checker when a variable expression cannot
 be resolved. | 
| void | onMethodSelection(Expression expression,
                 MethodNode target)Allows the extension to listen to method selection events. | 
| void | removeHandler(TypeCheckingExtension handler) | 
| void | setup()Subclasses should implement this method whenever they need to perform
 special checks before the type checker starts working. |
