Detailed Description

response handler that builds an OPeNDAP DDS response object

A request 'get dds 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 DDS response object. It then transmits the DDS object using the method send_dds on a specified transmitter object.

Member Function Documentation

◆ dump()

void BESDDSResponseHandler::dump ( 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 122 of file BESDDSResponseHandler.cc.

◆ execute()

void BESDDSResponseHandler::execute ( BESDataHandlerInterface dhi)
virtual

executes the command 'get dds for def_name;' by executing the request for each container in the specified definition.

For each container in the specified definition go to the request handler for that container and have it add to the OPeNDAP DDS response object. The DDS response object is created within this method and passed to the request handler list.

Parameters
dhistructure that holds request and response information

BESDataHandlerInterface
BESDDSResponse
BESRequestHandlerList

Implements BESResponseHandler.

◆ get_name()

virtual string BESResponseHandler::get_name ( ) const
inlinevirtualinherited

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

Definition at line 156 of file BESResponseHandler.h.

◆ 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

BESResponseObject

Definition at line 53 of file BESResponseHandler.cc.

◆ 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 BESDDSResponseHandler::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_dds method on the specified transmitter object.

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