Member Function Documentation

virtual 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 ACE_ENV_ARG_DECL_WITH_DEFAULTS

) 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

virtual 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 ACE_ENV_ARG_DECL_WITH_DEFAULTS

) 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.

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

AVStreams::StreamEndPoint_out sep ACE_ENV_ARG_DECL_WITH_DEFAULTS

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

virtual CORBA::Boolean TAO_StreamCtrl::modify_QoS ( AVStreams::streamQoS & new_qos,

const AVStreams::flowSpec &the_spec ACE_ENV_ARG_DECL_WITH_DEFAULTS

) 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.

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

Start the transfer of data in the stream. Empty the_spec means apply operation to all flows
Reimplemented from TAO_Basic_StreamCtrl.

virtual void TAO_StreamCtrl::stop ( const AVStreams::flowSpec &the_spec ACE_ENV_ARG_DECL_WITH_DEFAULTS ) 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.

virtual void TAO_StreamCtrl::unbind ( ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS ) throw (CORBA::SystemException, AVStreams::streamOpFailed) [virtual]

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

virtual void TAO_StreamCtrl::unbind_dev ( AVStreams::MMDevice_ptr dev,

const AVStreams::flowSpec &the_spec ACE_ENV_ARG_DECL_WITH_DEFAULTS

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

virtual void TAO_StreamCtrl::unbind_party ( AVStreams::StreamEndPoint_ptr the_ep,

const AVStreams::flowSpec &the_spec ACE_ENV_ARG_DECL_WITH_DEFAULTS

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

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