- ## Method Details

  - ### setCurrent

    public void setCurrent(String value)
    Set the current string.

  - ### getCurrent

    public String getCurrent()
    Get the current string.

  - ### setCurrent

    public void setCurrent(char[] text, int length)
    Set the current string.
    Parameters:
      `text` - character array containing input
      `length` - valid length of text.

  - ### getCurrentBuffer

    public char[] getCurrentBuffer()
    Get the current buffer containing the stem.

    NOTE: this may be a reference to a different character array than the one originally provided with setCurrent, in the exceptional case that stemming produced a longer intermediate or result string.

    It is necessary to use `getCurrentBufferLength()` to determine the valid length of the returned buffer. For example, many words are stemmed simply by subtracting from the length to remove suffixes.

    public int getCurrentBufferLength()
    Get the valid length of the character array in `getCurrentBuffer()`.
    Returns:
      valid length of the array.
