void BESShowContainersResponseHandler::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 BESShowContainersResponseHandler::execute BESDataHandlerInterface dhi  )  [virtual]
 

executes the command 'show containers;' by returning the list of currently defined containers in all container stores

This response handler knows how to retrieve information about all containers stored with any container storage objects. This response handler creates a BESInfo response object to store the container information.

Parameters:
dhi structure that holds request and response information
Exceptions:
BESHandlerException if there is a problem building the response
BESResponseException if a fatal error occurs building the response

virtual const 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 * BESShowContainersResponseHandler::ShowContainersResponseBuilder string  handler_name  )  [static]
 

void BESShowContainersResponseHandler::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 (BESInfo) then transmit it as text.

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