void BESStatusResponseHandler::dump ( ostream &  strm  )  const [virtual]

dumps information about this object

Displays the pointer value of this instance

Parameters:
strm C++ i/o stream to dump the information to

Reimplemented from BESResponseHandler.

void BESStatusResponseHandler::execute ( BESDataHandlerInterface dhi  )  [virtual]

executes the command 'show status;' by returning the status of the server process

This response handler knows how to retrieve the status for the server process handing this clients requests from BESStatus and stores it in a BESInfo informational response object.

Parameters:
dhi structure that holds request and response information

BESStatus

Implements BESResponseHandler.

virtual string BESResponseHandler::get_name (  )  const [inline, virtual, inherited]

return the name of this response object

This name is used to determine which response handler can handle a requested responose, such as das, dds, ddx, tab, info, version, help, etc...

Returns:
response name

BESResponseObject * BESResponseHandler::get_response_object (  )  [virtual, inherited]

return the current response object

Returns the current response object, null if one has not yet been created. The response handler maintains ownership of the response object.

Returns:
current response object

BESResponseObject

BESResponseObject * BESResponseHandler::set_response_object ( BESResponseObject o  )  [virtual, inherited]

replaces the current response object with the specified one, returning the current response object

This method is used to replace the response object with a new one, for example if during aggregation a new response object is built from the current response object.

The caller of set_response_object now owns the returned response object. The new response object is now owned by the response object.

Parameters:
o new response object used to replace the current one
Returns:
the response object being replaced

BESResponseHandler * BESStatusResponseHandler::StatusResponseBuilder ( const string &  name  )  [static]

void BESStatusResponseHandler::transmit ( BESTransmitter transmitter,
BESDataHandlerInterface dhi 
) [virtual]

transmit the response object built by the execute command using the specified transmitter object

If a response object was built then transmit it as text using the specified transmitter object.

Parameters:
transmitter object that knows how to transmit specific basic types
dhi structure that holds the request and response information
