NAME

19       POE::Filter::HTTPChunk - Non-blocking incremental HTTP chunk parser.
20

VERSION

22       version 0.949
23

SYNOPSIS

25         # Not a complete program.
26         use POE::Filter::HTTPChunk;
27         use POE::Wheel::ReadWrite;
28         sub setup_io {
29           $_[HEAP]->{io_wheel} = POE::Wheel::ReadWrite->new(
30             Filter => POE::Filter::HTTPChunk->new(),
31             # See POE::Wheel::ReadWrite for other required parameters.
32           );
33         }
34

DESCRIPTION

36       This filter parses HTTP chunks from a data stream.  It's used by
37       POE::Component::Client::HTTP to do the bulk of the low-level HTTP
38       parsing.
39

CONSTRUCTOR

41   new
42       "new" takes no parameters and returns a shiny new
43       POE::Filter::HTTPChunk object ready to use.
44

METHODS

46       POE::Filter::HTTPChunk supports the following methods.  Most of them
47       adhere to the standard POE::Filter API.  The documentation for
48       POE::Filter explains the API in more detail.
49
50   get_one_start ARRAYREF
51       Accept an arrayref containing zero or more raw data chunks.  They are
52       added to the filter's input buffer.  The filter will attempt to parse
53       that data when get_one() is called.
54
55         $filter_httpchunk->get_one_start(\@stream_data);
56
57   get_one
58       Parse a single HTTP chunk from the filter's input buffer.  Data is
59       entered into the buffer by the get_one_start() method.  Returns an
60       arrayref containing zero or one parsed HTTP chunk.
61
62         $ret_arrayref = $filter_httpchunk->get_one();
63
64   get_pending
65       Returns an arrayref of stream data currently pending parsing.  It's
66       used to seamlessly transfer unparsed data between an old and a new
67       filter when a wheel's filter is changed.
68
69         $pending_arrayref = $filter_httpchunk->get_pending();
