Detailed Description

response handler that builds an OPeNDAP DAS response object

A request 'get das 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 DAS response object. It then transmits the DAS object using the method send_das on the speicifed transmitter object.

Member Function Documentation

◆ dump()

void BESDASResponseHandler::dump ( std::ostream &  strm) const
virtual

dumps information about this object

Displays the pointer value of this instance

Parameters
strmC++ i/o stream to dump the information to

Reimplemented from BESResponseHandler.

Definition at line 160 of file BESDASResponseHandler.cc.

◆ execute()

void BESDASResponseHandler::execute ( BESDataHandlerInterface dhi)
virtual

executes the command <get type="das" definition=...>

For each container in the specified definition go to the request handler for that container and have it add to the OPeNDAP DAS response object. The DAS response object is built within this method and passed to the request handler list. This command will read the DAS from the MDS if that has been configured and the response is found there.

DAS responses are added to the MDS when a request for either the DMR or DDS is made.

Parameters
dhistructure that holds request and response information

◆ get_response_object()

BESResponseObject * BESResponseHandler::get_response_object ( )
virtualinherited

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

◆ transmit()

void BESDASResponseHandler::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 using the send_das method on the transmitter object.

Parameters
transmitterobject that knows how to transmit specific basic types
dhistructure that holds the request and response information
