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