Establish a connection between two streamendpoints. This can be used if the streamendpoints have been created independent of a MMDevice

)  throw (CORBA::SystemException, AVStreams::streamOpFailed, AVStreams::noSuchFlow, AVStreams::QoSRequestFailed) [virtual]
 

Establish a stream between a_party and b_party, with qos the_qos, and for the flows in the_flows if the_flows is empty, bind all the flows Causes a connection to be established between the StreamEndpoints. Returns success/failure

virtual void TAO_StreamCtrl::destroy (  const AVStreams::flowSpec &the_spec  ACE_ENV_ARG_DECL_WITH_DEFAULTS  )  throw (CORBA::SystemException, AVStreams::noSuchFlow) [virtual]
 

Tears down the stream. This will close the connection, and delete the streamendpoint and vdev associated with this stream Empty the_spec means apply operation to all flows

Reimplemented from TAO_Basic_StreamCtrl.
