CORBA::Boolean TAO_StreamCtrl::bind ( AVStreams::StreamEndPoint_A_ptr a_party,
AVStreams::StreamEndPoint_B_ptr b_party,
AVStreams::streamQoS & the_qos,
const AVStreams::flowSpec & the_flows,
CORBA::Environment & env = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::streamOpFailed, AVStreams::noSuchFlow, AVStreams::QoSRequestFailed) [virtual]
 

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

CORBA::Boolean TAO_StreamCtrl::bind_devs ( AVStreams::MMDevice_ptr a_party,
AVStreams::MMDevice_ptr b_party,
AVStreams::streamQoS & the_qos,
const AVStreams::flowSpec & the_flows,
CORBA::Environment & env = CORBA::Environment::default_environment () ) 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

void TAO_StreamCtrl::destroy ( const AVStreams::flowSpec & the_spec,
CORBA::Environment & env = CORBA::Environment::default_environment () ) 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.

AVStreams::VDev_ptr TAO_StreamCtrl::get_related_vdev ( AVStreams::MMDevice_ptr adev,

const AVStreams::flowSpec & the_spec,
CORBA::Environment & env = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::noSuchFlow, AVStreams::QoSRequestFailed) [virtual]
 

Changes the QoS associated with the stream Empty the_spec means apply operation to all flows.

Reimplemented from TAO_Basic_StreamCtrl.

Reimplemented from TAO_Basic_StreamCtrl.

void TAO_StreamCtrl::stop ( const AVStreams::flowSpec & the_spec,
CORBA::Environment & env = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::noSuchFlow) [virtual]
 

Stop the transfer of data of the stream Empty the_spec means apply operation to all flows.

Reimplemented from TAO_Basic_StreamCtrl.

void TAO_StreamCtrl::unbind ( CORBA::Environment & env = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::streamOpFailed) [virtual]
 

unbind the stream. Same effect as Basic_StreamCtrl::destroy ().

void TAO_StreamCtrl::unbind_dev ( AVStreams::MMDevice_ptr dev,
const AVStreams::flowSpec & the_spec,
CORBA::Environment & ACE_TRY_ENV = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::streamOpFailed, AVStreams::noSuchFlow) [virtual]

const AVStreams::flowSpec & the_spec,
CORBA::Environment & env = CORBA::Environment::default_environment () ) throw (CORBA::SystemException, AVStreams::streamOpFailed, AVStreams::noSuchFlow) [virtual]
 

Unbind the_ep from the stream. Empty the_spec means apply to all flows.
