        public void add​(java.lang.reflect.Method method)

        Parameters:
        method -
      • get

        public java.util.List get​(java.lang.String key)
        Return a list of methods with the same name.

        key -
        Returns:
        List list of methods
      • find

        public java.lang.reflect.Method find​(java.lang.String methodName,
                                             java.lang.Object[] args)
                                      throws MethodMap.AmbiguousException

        Find a method. Attempts to find the most specific applicable method using the algorithm described in the JLS section 15.12.2 (with the exception that it can't distinguish a primitive type argument from an object type argument, since in reflection primitive type arguments are represented by their object counterparts, so for an argument of type (say) java.lang.Integer, it will not be able to decide between a method that takes int and a method that takes java.lang.Integer as a parameter.

        This turns out to be a relatively rare case where this is needed - however, functionality like this is needed.

        Parameters:
        methodName - name of method
        args - the actual arguments with which the method is called
        Returns:
        the most specific applicable method, or null if no method is applicable.
        Throws:
        MethodMap.AmbiguousException - if there is more than one maximally specific applicable method
