Member Function Documentation

BESResponseHandler * BESShowCommand::parse_request ( BESTokenizer tokenizer,
BESDataHandlerInterface dhi 
) [virtual]

knows how to parse a show request

This class knows how to parse a show request, building a sub response handler that actually knows how to build the requested response object, such as for show help or show version.

A show request looks like:

get <info_type>;

where info_type is the type of information that the user is requesting, such as help or version

This parse method creates the sub response handler that knows how to create the specified information, such as creating HelpResponseHandler.

Parameters:
tokenizer holds on to the list of tokens to be parsed
dhi structure that holds request and response information
Exceptions:
BESSyntaxUserError if there is a problem parsing the request
