    • getConstructor

      public static Constructor getConstructor(Class targetClass, Class[] argTypes) throws SecurityException, NoSuchMethodException
      Class.getConstructor() finds only the entry point (if any) _exactly_ matching the specified argument types. Our implmentation can decide between several imperfect matches, using the same search algorithm as the Java compiler. Note that all constructors are static by definition, so isStaticReference is true.
      Throws:
      NoSuchMethodException - if constructor not found.
      SecurityException
    • getMethod

      public static Method getMethod(Class target, String methodName, Class[] argTypes, boolean isStaticReference) throws SecurityException, NoSuchMethodException
      Throws:
      SecurityException
      NoSuchMethodException
    • getMethod

      public static Method getMethod(Object target, String methodName, Class[] argTypes) throws SecurityException, NoSuchMethodException
      Class.getMethod() finds only the entry point (if any) _exactly_ matching the specified argument types. Our implmentation can decide between several imperfect matches, using the same search algorithm as the Java compiler. This version emulates the compiler behavior by allowing lookup to be performed against either a class or an instance -- classname.foo() must be a static method call, instance.foo() can invoke either static or instance methods.
      Parameters:
      target - object on which call is to be made
      methodName - name of method I'm lookin' for
      argTypes - array of argument types of method
      Returns:
      the desired method
      Throws:
      SecurityException - if security violation
      NoSuchMethodException - if no such method
