- - ### Constructor Detail

    - #### CharBuffer

          public CharBuffer(char[] chars)

      Creates instance of CharBuffer already filled by chars.
      Parameters:
        `chars` -

    - #### CharBuffer

          public CharBuffer(int cacheSize)

      Creates instance of CharBuffer with char array of required length.
      Parameters:
        `cacheSize` - length of char array

  - ### Method Detail

    - #### append

          public CharBuffer append(char c)

      Appends character to array chars if there are unfilled positions in it. Otherwise creates next link in the chain, and appends the character to it.
      Parameters:
        `c` -
      Returns:
        instance of CharBuffer to which character was appended.

    - #### append

          public CharBuffer append(char[] cs,
                          int off,
                          int len)

      Appends segment of a char array to array if there are unfilled positions in it. Otherwise creates next link in the chain, and appends data to it.
      Parameters:
        `cs` -
        `off` -
        `len` -
      Returns:
        instance of CharBuffer to which char array was appended.

    - #### getChars

          public char[] getChars()

      Returns:
        stored char array

    - #### getCharAt

          public char getCharAt(int index)

      Returns character at index. No check is fulfilled to provide high speed.
      Parameters:
        `index` -
      Returns:
        character at index

    - #### getUsedSize
