executes the command 'show catalog|leaves [for <node>];' by returning nodes or leaves at the top level or at the specified node.

The response object BESInfo is created to store the information.

Parameters:
dhistructure that holds request and response information

return the name of this response object

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

Returns:
response name

BESResponseObject * BESResponseHandler::get_response_object ( )

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 * BESResponseHandler::set_response_object ( BESResponseObject o)
virtualinherited

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:
onew response object used to replace the current one
Returns:
the response object being replaced

void BESCatalogResponseHandler::transmit ( BESTransmitter transmitter,
BESDataHandlerInterface dhi

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

Parameters:
transmitterobject that knows how to transmit specific basic types
