AbstractMessageParserHC4.java 文件源码

/**
 * 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.
 *
 * @param inbuffer Session input buffer
 * @param 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.
 * @param 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.
 * @return array of HTTP headers
 * @param parser line parser to use. Can be <code>null</code>, in which case
 *  the default implementation of this interface will be used.
 *
 * @throws IOException in case of an I/O error
 * @throws HttpException in case of HTTP protocol violation
