NAME

POE::Filter::HTTPChunk - Non-blocking incremental HTTP chunk parser.

SYNOPSIS

   # Not a complete program.
   use POE::Filter::HTTPChunk;
   use POE::Wheel::ReadWrite;
   sub setup_io {
     $_[HEAP]->{io_wheel} = POE::Wheel::ReadWrite->new(
       Filter => POE::Filter::HTTPChunk->new(),
       # See POE::Wheel::ReadWrite for other required parameters.
     );
   }

DESCRIPTION

This filter parses HTTP chunks from a data stream. It's used by POE::Component::Client::HTTP to do the bulk of the low-level HTTP parsing.

CONSTRUCTOR

new

"new" takes no parameters and returns a shiny new POE::Filter::HTTPChunk object ready to use.

METHODS

POE::Filter::HTTPChunk supports the following methods. Most of them adhere to the standard POE::Filter API. The documentation for POE::Filter explains the API in more detail.

get_one_start ARRAYREF

Accept an arrayref containing zero or more raw data chunks. They are added to the filter's input buffer. The filter will attempt to parse that data when get_one() is called. 
   $filter_httpchunk->get_one_start(\@stream_data);

get_one

Parse a single HTTP chunk from the filter's input buffer. Data is entered into the buffer by the get_one_start() method. Returns an arrayref containing zero or one parsed HTTP chunk. 
   $ret_arrayref = $filter_httpchunk->get_one();

get_pending

Returns an arrayref of stream data currently pending parsing. It's used to seamlessly transfer unparsed data between an old and a new filter when a wheel's filter is changed. 
   $pending_arrayref = $filter_httpchunk->get_pending();
