      • containsKey

        public boolean containsKey​(char k)
        Description copied from interface: Char2DoubleFunction
        Returns true if this function contains a mapping for the specified key.

        Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

        Specified by:
        containsKey in interface Char2DoubleFunction
        Parameters:
        k - the key.
        Returns:
        true if this function associates a value to key.

      • size

        public int size()
        Description copied from interface: Function
        Returns the intended number of keys in this function, or -1 if no such number exists.

        Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.

        Specified by:
        size in interface Function<Character,​Double>
        Returns:
        the intended number of keys in this function, or -1 if that number is not available.
