Structure storing information used by the BES to handle the request.
void make_copy(const BESDataHandlerInterface &copy_from)
deprecated
std::map< std::string, std::string > data
the map of string data that will be required for the current request.
std::string action
the response object requested, e.g. das, dds
virtual BESResponseHandler * find_handler(const std::string &handler)
returns the response handler with the given name from the list
error thrown if there is a user syntax error in the request or any other user error
static void del_command(const std::string &cmd_str)
Deletes the command called cmd_str from the list of possible commands.
BESXMLCommand(const BESDataHandlerInterface &base_dhi)
Creates a BESXMLCommand document given a base data handler interface object.
virtual void dump(std::ostream &strm) const
dumps information about this object
virtual void set_response()
The request has been parsed, use the command action name to set the response handler.
static void add_command(const std::string &cmd_str, p_xmlcmd_builder cmd)
Add a command to the possible commands allowed by this BES.
std::string d_cmd_log_info
Used only for the log.
