Class ReflectorLoader

  • public class ReflectorLoader
    extends ClassLoader
    Reflector creation helper. This class is used to define the Reflector classes. For each ClassLoader such a loader will be created by MetaClass. Special about this loader is, that it knows the classes form the Groovy Runtime. The Reflector class is resolved in different ways: During the definition of a class Reflector will resolve to the Reflector class of the runtime, even if there is another Reflector class in the parent loader. After the new class is defined Reflector will resolve like other Groovy classes. This loader is able to resolve all Groovy classes even if the parent does not know them, but the parent serves first (Reflector during a class definition is different).

      • loadClass

        protected Class loadClass​(String name,
                                  boolean resolve)
                           throws ClassNotFoundException
        Loads a class per name. Unlike a normal loadClass this version behaves different during a class definition. In that case it checks if the class we want to load is Reflector and returns class if the check is successful. If it is not during a class definition it just calls the super class version of loadClass.
