Detailed Description

response handler that builds an OPeNDAP Dap4 data response

This ResponseHandler is used to build DAP4 data responses.

This class looks in the MDS for cached/stored DMR++ responses and, if found, will re-direct the request to the DMR++ requestHandler, regardless of the dataset's format and/or RequestHandler as specified by the bes.conf TypeMatch configuration. However, this can be suppressed using a configuration parameter in the bes.conf file. If the bes key BES.Use.Dmrpp is not yes, the handler does not look in the MDS for DMR++ responses and no attempt to redirect the request is made. The bes key BES.Dmrpp.Name should be set to the name of the DMR++ handler used in the key BES.modules.

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

◆ get_use_dmrpp()

virtual bool BESDap4ResponseHandler::get_use_dmrpp ( ) const

Is the BES.Use.Dmrpp key set in the bes.conf?

Returns
True or false.

◆ 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 BESDap4ResponseHandler::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_dmr method on the transmitter object.

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