Member Function Documentation

virtual void TAO_Basic_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 in TAO_StreamCtrl.

CORBA::Object_ptr TAO_Basic_StreamCtrl::get_flow_connection ( const char *flow_name ACE_ENV_ARG_DECL_WITH_DEFAULTS ) throw (CORBA::SystemException, AVStreams::noSuchFlow, AVStreams::notSupported) [virtual]

Not implemented in the light profile, will raise the notsupported exception

virtual CORBA::Boolean TAO_Basic_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 in TAO_StreamCtrl.

virtual void TAO_Basic_StreamCtrl::push_event ( const struct CosPropertyService::Property &the_event ACE_ENV_ARG_DECL_WITH_DEFAULTS ) throw (CORBA::SystemException) [virtual]

Used by StreamEndPoint and VDev to inform StreamCtrl of events. E.g., loss of flow, reestablishment of flow, etc..

virtual void TAO_Basic_StreamCtrl::set_flow_connection ( const char * flow_name,

CORBA::Object_ptr flow_connection ACE_ENV_ARG_DECL_WITH_DEFAULTS

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

Not implemented in the light profile, will raise the notsupported exception

void TAO_Basic_StreamCtrl::set_FPStatus ( const AVStreams::flowSpec & the_spec,

const char * fp_name,

const CORBA::Any &fp_settings ACE_ENV_ARG_DECL_WITH_DEFAULTS

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

Used to control the flow protocol parameters.

virtual void TAO_Basic_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 in TAO_StreamCtrl.

virtual void TAO_Basic_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 in TAO_StreamCtrl.
