Method Detail

• append

  Appendable append(CharSequence csq)
                    throws IOException

  Appends the specified character sequence to this Appendable.

  Depending on which class implements the character sequence csq, the entire sequence may not be appended. For instance, if csq is a CharBuffer then the subsequence to append is defined by the buffer's position and limit.

  Parameters:

  csq - The character sequence to append. If csq is null, then the four characters "null" are appended to this Appendable.

  Returns:

  A reference to this Appendable

  Throws:

  IOException - If an I/O error occurs

• append

  Appendable append(CharSequence csq,
                  int start,
                  int end)
                    throws IOException

  Appends a subsequence of the specified character sequence to this Appendable.

  An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation

       out.append(csq.subSequence(start, end)) 

  Parameters:

  csq - The character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null".

  start - The index of the first character in the subsequence

  end - The index of the character following the last character in the subsequence

  Returns:

  A reference to this Appendable

  Throws:

  IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()

  IOException - If an I/O error occurs

• append

  Appendable append(char c)
                    throws IOException

  Appends the specified character to this Appendable.

  Parameters:

  c - The character to append

  Returns:

  A reference to this Appendable

  Throws:

  IOException - If an I/O error occurs
