Detailed Description

response handler that builds an OPeNDAP Data DDS object

A request 'get data 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 response object. It then transmits the response object using the method send_data on the transmitter object.

Member Function Documentation

void BESDataResponseHandler::execute ( BESDataHandlerInterface dhi  )  [virtual]

executes the command 'get data for <def_name>' by executing the request for each container in the specified definition

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

Parameters:
dhi structure that holds request and response information
Exceptions:
BESHandlerException if there is a problem building the response object
BESResponseException upon fatal error building the response object

void BESDataResponseHandler::transmit ( BESTransmitter transmitter,
BESDataHandlerInterface dhi 
) [virtual]

transmit the response object built by the execute command

If a response object was built then transmit it using the send_data method on the specified transmitter object.

Parameters:
transmitter object that knows how to transmit specific basic types
dhi structure that holds the request and response information

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.

Returns:
current 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.

Parameters:
o new response object used to replace the current one
Returns:
the response object being replaced

virtual const 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...

Returns:
response name
