| Destructor.

## 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.
