• Method Summary

  All Methods

  Modifier and Type	Method	Description
  Appendable	append (char c)	Appends the specified character to this Appendable.
  Appendable	append (CharSequence csq)	Appends the specified character sequence to this Appendable.
  Appendable	append (CharSequence csq, int start, int end)	Appends a subsequence of the specified character sequence to this Appendable.

• 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
