      @Deprecated public V apply(int operand)
      Deprecated.
      Please use the corresponding type-specific method instead.

    • apply

      @Deprecated public V apply(Character key)
      Deprecated.
      Please use the corresponding type-specific method instead.
      This is equivalent to calling Function.get(Object).

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

      public V defaultReturnValue()
      Description copied from interface: Char2ObjectFunction
      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 Char2ObjectFunction<V>
      Returns:
      the current default return value.
    • defaultReturnValue

      public void defaultReturnValue(V defRetValue)
      Description copied from interface: Char2ObjectFunction
      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 Char2ObjectFunction<V>
      Parameters:
      defRetValue - the new default return value.

    • containsKey

      public boolean containsKey(char k)
      Description copied from interface: Char2ObjectFunction
      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 Char2ObjectFunction<V>
      Parameters:
      k - the key.
      Returns:
      true if this function associates a value to key.
      See Also:
    • containsKey

      @Deprecated public boolean containsKey(Object k)
      Deprecated.
      Description copied from interface: Char2ObjectFunction
      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 Char2ObjectFunction<V>
      Specified by:
      containsKey in interface Function<Character,V>
      Parameters:
      k - the key.
      Returns:
      true if this function associates a value to key.

      Parameters:
      k - the key.
