Detailed Description

response handler that builds an OPeNDAP DDX object

A request 'get ddx for <def_name>;' will be handled by this response handler. Given a definition name it determines what containers are to be used to build the OPeNDAP DDX response object that includes attribute information found in a DAS object and data definitions found in a DDS object. It also knows how to transmit the DDX response object using the specified transmitter object in the transmit method.

dump()

void BESDDXResponseHandler::dump ( std::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

execute()

void BESDDXResponseHandler::execute ( BESDataHandlerInterface & dhi )

virtual

executes the command 'get ddx for def_name;'

For each container in the specified definition go to the request handler for that container and have it first add to the OPeNDAP DDS response object. Once the DDS object has been filled in, repeat the process but this time for the OPeNDAP DAS response object. Then add the attributes from the DAS object to the DDS object.

Parameters

dhi	structure that holds request and response information

get_response_object()

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

set_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

o	new response object used to replace the current one

Returns

the response object being replaced

transmit()

void BESDDXResponseHandler::transmit ( BESTransmitter * transmitter, BESDataHandlerInterface & dhi )

virtual

transmit the response object built by the execute command

If a response object was built then transmit it using the send_ddx method on the specified transmitter object.

Parameters

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