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.

void BESDASResponseHandler::execute | ( | BESDataHandlerInterface & | dhi | ) | [virtual] |
executes the command 'get das 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.
dhi | structure that holds request and response information |

virtual string BESResponseHandler::get_name | ( | ) | const [inline, virtual, inherited] |
return the name of this response object
This name is used to determine which response handler can handle a requested responose, such as das, dds, ddx, tab, info, version, help, etc...

BESResponseObject * BESResponseHandler::get_response_object | ( | ) | [virtual, inherited] |
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.

BESResponseObject * BESResponseHandler::set_response_object | ( | BESResponseObject * | o | ) | [virtual, inherited] |
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.
o | new response object used to replace the current one |

void BESDASResponseHandler::transmit | ( | BESTransmitter * | transmitter, | |

) | [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.
transmitter | object that knows how to transmit specific basic types | |
