- an int specifying the initial buffer size.IllegalArgumentException

out
- the output stream to write toIOException
- If an I/O error occurs.public FastCharArrayWriter append(CharSequence csq)
An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation
out.write(csq.toString())
Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking the toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.

csq
- The character sequence to append. If csq is
null, then the four characters "null" are
appended to this writer.public FastCharArrayWriter append(CharSequence csq, int start, int end)
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.write(csq.subSequence(start, end).toString())

appended. If csq is null, then characters
will be appended as if csq contained the four
