    • Method Detail

      • add

        public void add​(Method method)
        Add a method to a list of methods by name. For a particular class we are keeping track of all the methods with the same name.
        Parameters:
        method -
      • get

        public List<Method> get​(String key)
        Return a list of methods with the same name.
        Parameters:
        key -
        Returns:
        List list of methods
      • find

        public Method find​(String methodName,
                           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
      • getTopMostMethodDeclaration

        public static Method getTopMostMethodDeclaration​(Method method)
        Once we identified a best match of a specific call, walk up the chain of inheritance to find the top-most declaration for this method. This is needed to avoid IllegalAccessException, when a public API method is implemented by a class which is not exported.
        Parameters:
        method -
        Returns:
