    • getAllMethods

      Set<CtMethod<?>> getAllMethods()
      Return all the methods that can be called on an instance of this type. It recursively collects all methods (both concrete and abstract) from all super-classes and all super-interfaces. It deduplicates methods with the same signature, which are defined several times somewhere in the type hierarchy. Warning: this method can be really slow due to signature deduplication. It includes all methods: the methods of types whose source code is in the Spoon model, the methods of types from the JDK and from libraries present in the classpath, the methods of java.lang.Object (for all CtClass objects). However, in noclasspath mode, it does not include methods from unknown types. If methods are overridden somewhere in the type hierarchy, it returns only top methods (ie method definitions).

    • clone

      CtType<T> clone()
      Description copied from interface: CtElement
      Clone the element which calls this method in a new object. Note that that references are kept as is, and thus, so if you clone whole classes or methods, some parts of the cloned element (eg executable references) may still point to the initial element. In this case, consider using methods Refactoring.copyType(CtType) and Refactoring.copyMethod(CtMethod) instead which does additional work beyond cloning.
      Specified by:
      clone in interface CtElement
      Specified by:
      clone in interface CtNamedElement
    • copyType

      CtType<?> copyType()
      Copy the type, where copy means cloning + porting all the references in the clone from the old type to the new type. The copied type is added to the same package (and this to the factory as well). A new unique method name is given for each copy, and this method can be called several times.
