use of org.apache.http.util.CharArrayBuffer in project XobotOS by xamarin.

the class AbstractMessageParser method parseHeaders.

/**
     * 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
     * @return array of HTTP headers
     *
