      • containsKey

        public boolean containsKey​(int key)
        Description copied from interface: Int2ObjectFunction
        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 Int2ObjectFunction<V>
        Parameters:
        key - the key.
        Returns:
        true if this function associates a value to key.
