Class Overview
Abstract base class for HTTP message parsers that obtain input from
an instance of SessionInputBuffer.
The following parameters can be used to customize the behavior of this
class:

HttpMessage

parse()
Generates an instance of HttpMessage from the underlying data
source. |

static
Header[]
|
parseHeaders(SessionInputBuffer inbuffer, int maxHeaderCount, int maxLineLen, LineParser parser, List headerLines)
Parses HTTP headers from the data receiver stream according to the generic
format as given in Section 3.1 of RFC 822, RFC-2616 Section 4 and 19.3.

parseHeaders(SessionInputBuffer inbuffer, int maxHeaderCount, int maxLineLen, LineParser parser)
Parses HTTP headers from the data receiver stream according to the generic
format as given in Section 3.1 of RFC 822, RFC-2616 Section 4 and 19.3.

Fields
Public Constructors

Header[]
parseHeaders
(SessionInputBuffer inbuffer, int maxHeaderCount, int maxLineLen, LineParser parser, List headerLines)
Parses HTTP headers from the data receiver stream according to the generic
format as given in Section 3.1 of RFC 822, RFC-2616 Section 4 and 19.3.
Parameters
| inbuffer
| Session input buffer |
| maxHeaderCount
| maximum number of headers allowed. If the number
of headers received from the data stream exceeds maxCount value, an
IOException will be thrown. Setting this parameter to a negative value
or zero will disable the check. |
| maxLineLen
| maximum number of characters for a header line,
including the continuation lines. Setting this parameter to a negative
value or zero will disable the check. |
| parser
| line parser to use. |
| headerLines
| List of header lines. This list will be used to store
intermediate results. This makes it possible to resume parsing of
headers in case of a java.io.InterruptedIOException. |

Header[]
parseHeaders
(SessionInputBuffer inbuffer, int maxHeaderCount, int maxLineLen, LineParser parser)
Parses HTTP headers from the data receiver stream according to the generic
format as given in Section 3.1 of RFC 822, RFC-2616 Section 4 and 19.3.
Parameters
| inbuffer
| Session input buffer |
| maxHeaderCount
| maximum number of headers allowed. If the number
of headers received from the data stream exceeds maxCount value, an
IOException will be thrown. Setting this parameter to a negative value
or zero will disable the check. |
| maxLineLen
| maximum number of characters for a header line,
including the continuation lines. Setting this parameter to a negative
value or zero will disable the check. |
| parser
| line parser to use. Can be null, in which case
the default implementation of this interface will be used. |
Protected Methods
Subclasses must override this method to generate an instance of
HttpMessage based on the initial input from the session buffer.
Usually this method is expected to read just the very first line or
the very first valid from the data stream and based on the input generate
an appropriate instance of HttpMessage.
Parameters
| sessionBuffer
| the session input buffer. |
Returns
- HTTP message based on the input from the session buffer.
