Class Int2CharFunctions.SynchronizedFunction

    • Method Detail

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

        public char defaultReturnValue()
        Description copied from interface: Int2CharFunction
        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 Int2CharFunction
        Returns:
        the current default return value.
      • defaultReturnValue

        public void defaultReturnValue​(char defRetValue)
        Description copied from interface: Int2CharFunction
        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 Int2CharFunction
        Parameters:
        defRetValue - the new default return value.

      • containsKey

        public boolean containsKey​(int k)
        Description copied from interface: Int2CharFunction
        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 Int2CharFunction
        Parameters:
        k - the key.
        Returns:
        true if this function associates a value to key.

        Function.containsKey(Object)
      • containsKey

        @Deprecated
        public boolean containsKey​(Object k)
        Deprecated.
        Description copied from interface: Int2CharFunction
        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<Integer,​Character>
        Specified by:
        containsKey in interface Int2CharFunction
        Parameters:
        k - the key.
        Returns:
        true if this function associates a value to key.

      • get

        @Deprecated
        public Character 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<Integer,​Character>
        Specified by:
        get in interface Int2CharFunction
        Parameters:
        k - the key.
        Returns:
        the corresponding value, or null if no value was present for the given key.

        Map.get(Object)
      • remove

        @Deprecated
        public Character remove​(Object k)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Removes this key and the associated value from this function if it is present (optional operation).
        Specified by:
        remove in interface Function<Integer,​Character>
        Specified by:
        remove in interface Int2CharFunction
        Parameters:
        k - the key.
        Returns:
        the old value, or null if no value was present for the given key.
