Method Details- 
setuppublic void setup()Description copied from class:TypeCheckingExtensionSubclasses should implement this method whenever they need to perform special checks before the type checker starts working.- Overrides:
- setupin class- TypeCheckingExtension
 
- 
handleMissingMethodpublic java.util.List<MethodNode> handleMissingMethod(ClassNode receiver, java.lang.String name, ArgumentListExpression argumentList, ClassNode[] argumentTypes, MethodCall call)Description copied from class:TypeCheckingExtensionThis method is called by the type checker when a method call cannot be resolved. Extensions may override this method to handle missing methods and prevent the type checker from throwing an error.- Overrides:
- handleMissingMethodin class- TypeCheckingExtension
- Parameters:
- receiver- the type of the receiver
- name- the name of the called method
- argumentList- the list of arguments of the call
- argumentTypes- the types of the arguments of the call
- call- the method call itself, if needed
- Returns:
- an empty list if the extension cannot resolve the method, or a list of potential methods if the extension finds candidates. This method must not return null.
