[erlang-questions] SAX-like JSON Parser for Erlang

This module looks really good. The documentation mentions "incomplete" 
data. I assume this ti be a case where we want to read data from an HTTP 
response.
I could not find an exported method in the module that lets me pass a 
stearm to jsx and get event to fire when individual objects are read from 
the stream. Is this supported in the module?
 
Thanks,
Yash
