      • 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<K,​Byte>
        Returns:
        the intended number of keys in this function, or -1 if that number is not available.

      • defaultReturnValue

        public byte defaultReturnValue()
        Description copied from interface: Reference2ByteFunction
        Gets the default return value.

        This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

        Specified by:
        defaultReturnValue in interface Reference2ByteFunction<K>
        Returns:
        the current default return value.

      • defaultReturnValue

        public void defaultReturnValue​(byte defRetValue)
        Description copied from interface: Reference2ByteFunction
        Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
        Specified by:
        defaultReturnValue in interface Reference2ByteFunction<K>
        Parameters:
        defRetValue - the new default return value.
        See Also:
        Reference2ByteFunction.defaultReturnValue()

      • containsKey

        public boolean containsKey​(Object k)
        Description copied from interface: Function
        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. This default implementation, in particular, always return true.

        Specified by:
        containsKey in interface Function<K,​Byte>
        Parameters:
        k - the key.
        Returns:
        true if this function associates a value to key.
        See Also:
        Map.containsKey(Object)

      • clear

        public void clear()
        Description copied from interface: Function
        Removes all associations from this function (optional operation).
        Specified by:
        clear in interface Function<K,​Byte>
        See Also:
        Map.clear()

      • put

        @Deprecated
public Byte put​(K k,
                Byte v)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Associates the specified value with the specified key in this function (optional operation).
        Specified by:
        put in interface Function<K,​Byte>
        Specified by:
        put in interface Reference2ByteFunction<K>
        Parameters:
        k - the key.
        v - the value.
        Returns:
        the old value, or null if no value was present for the given key.
        See Also:
        Map.put(Object,Object)

      • get

        @Deprecated
public Byte get​(Object k)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Returns the value associated by this function to the specified key.
        Specified by:
        get in interface Function<K,​Byte>
        Specified by:
        get in interface Reference2ByteFunction<K>
        Parameters:
        k - the key.
        Returns:
        the corresponding value, or null if no value was present for the given key.

        Specified by:
        remove in interface Reference2ByteFunction<K>
        Parameters:
        k - the key.
