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();
