Method Details

parseHead

protected HttpRequest parseHead(SessionInputBuffer sessionBuffer)
                         throws IOException,
HttpException,
ParseException

Description copied from class: AbstractMessageParser

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.

Specified by:

parseHead in class AbstractMessageParser<HttpRequest>

Parameters:

sessionBuffer - the session input buffer.

Returns:

HTTP message based on the input from the session buffer.

Throws:

IOException - in case of an I/O error.

HttpException - in case of HTTP protocol violation.

ParseException - in case of a parse error.
