Incremental encoders don't have any buffer.
Python 3.3a0 (default:3c7792ec4547+, May 26 2011, 00:24:51)
>>> import codecs
>>> enc=codecs.lookup('hz').incrementalencoder()
>>> enc.encode('\u8000')
b'~{R+'
>>> enc.reset()
>>> enc.encode('\u8000')
b'~{R+'
>>> enc.encode('', final=True)
b'~}'
>>> import io
>>> buffer=io.BytesIO()
>>> enc=codecs.lookup('hz').streamwriter(buffer)
>>> enc.write('\u8000')
>>> buffer.getvalue()
b'~{R+'
>>> enc.reset()
>>> buffer.getvalue()
b'~{R+~}'
IncrementalEncoder.reset() may mention that the output is discarded:
.. method:: reset()
Reset the encoder to the initial state. The output is discarded:
use the ``encode('', final=True)`` method to reset the encoder
and to get the output.
