                            | AbstractTypeCheckingExtension |  | 
                            | DefaultTypeCheckingExtension | The default type checking handler is used by the standard type checker and doesn't handle
 any of the type checking errors by default. | 
                            | ExtensionMethodNode | Represents method nodes which are used by the static type checker to virtually add methods
 coming from DGM-like methods. | 
                            | GroovyTypeCheckingExtensionSupport | Base class for type checking extensions written in Groovy. | 
                            | GroovyTypeCheckingExtensionSupport.TypeCheckingDSL |  | 
                            | Receiver |  | 
                            | SharedVariableCollector | A visitor which collects the list of variable expressions which are closure shared. | 
                            | SignatureCodecVersion1 | First implementation of an inferred type signature codec. | 
                            | StaticTypeCheckingSupport | Static support methods for StaticTypeCheckingVisitor. | 
                            | StaticTypeCheckingVisitor | The main class code visitor responsible for static type checking. | 
                            | StaticTypeCheckingVisitor.SignatureCodecFactory |  | 
                            | StaticTypeCheckingVisitor.VariableExpressionTypeMemoizer |  | 
                            | TraitTypeCheckingExtension | A type checking extension that will take care of handling errors which are specific to traits. | 
                            | TypeCheckingContext |  | 
                            | TypeCheckingContext.EnclosingClosure | Represents the context of an enclosing closure. | 
                            | TypeCheckingExtension | This interface defines a high-level API for handling type checking errors. |
