Detailed Description

response handler that builds an OPeNDAP WWW response object

A request 'get WWW 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 WWW response object. It then transmits the DataDDS object as WWW values.

◆ dump()

void BESResponseHandler::dump ( std::ostream & strm) const
overridevirtualinherited

◆ execute()

void BESWWWResponseHandler::execute ( BESDataHandlerInterface & dhi)
virtual

executes the command 'get html_form for <def_name>;' by executing the request for each container in the specified defnition.

For each container in the specified defnition 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.

Once the DAS has been filled in do the same for a DDS. We only need the description of the data and not the data itself.

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 BESWWWResponseHandler::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
