## Constructor & Destructor Documentation

TAO_FlowProducer::TAO_FlowProducer | ( | void |  | ) |

| default constructor

TAO_FlowProducer::TAO_FlowProducer | ( | const char * | flowname,

|  | const char * | format
| ) |

## Member Function Documentation

char * TAO_FlowProducer::connect_mcast | ( | AVStreams::QoS & | the_qos,
|  | CORBA::Boolean_out | is_met,
|  | const char * | address,
|  | const char *use_flow_protocol | ACE_ENV_ARG_DECL_WITH_DEFAULTS
| ) | throw (CORBA::SystemException, AVStreams::failedToConnect, AVStreams::notSupported, AVStreams::FPError, AVStreams::QoSRequestFailed)`[virtual]`

| connect to the multicast address, not implemented.

CORBA::Boolean TAO_FlowProducer::connect_to_peer | ( | AVStreams::QoS & | the_qos,
|  | const char * | address,
|  | const char *use_flow_protocol | ACE_ENV_ARG_DECL_WITH_DEFAULTS
| ) | throw (CORBA::SystemException, AVStreams::failedToConnect, AVStreams::FPError, AVStreams::QoSRequestFailed)`[virtual]`

| This should be implemented in both the FlowProducer and consumer and hence is pure virtual since we need to know the role of the flowendpoint to create appropriate protocol objects. eg. in SFP to create Producer Object/ Consumer Object. Implements TAO_FlowEndPoint.

virtual char* TAO_FlowProducer::get_rev_channel | ( | const char *pcol_name | ACE_ENV_ARG_DECL_WITH_DEFAULTS | ) | throw (CORBA::SystemException)`[virtual]`

get the reverse channel, to be used for feedback for protocols like UDP. @Naga: In the spec this is defined in the TAO_FlowProducer but it seems more reasonable for this to be in a FlowEndPoint since any of the flowendpoints can be made to listen. So in the case of UDP if the producer is listening and the consumer connects (logically) then the producer needs to know the reverse channel on its peer fep to send data to.

char * TAO_FlowProducer::go_to_listen | ( | AVStreams::QoS & | the_qos,
|  | CORBA::Boolean | is_mcast,
|  | AVStreams::FlowEndPoint_ptr | peer,
|  | char *&flowProtocol | ACE_ENV_ARG_DECL_WITH_DEFAULTS
| ) | throw (CORBA::SystemException, AVStreams::failedToListen, AVStreams::FPError, AVStreams::QoSRequestFailed)`[virtual]`

| This should be implemented in both the FlowProducer and consumer and hence is pure virtual since we need to know the role of the flowendpoint to create appropriate protocol objects. eg. in SFP to create Producer Object/ Consumer Object. Implements TAO_FlowEndPoint.

void TAO_FlowProducer::set_key | ( | const AVStreams::key &the_key | ACE_ENV_ARG_DECL_WITH_DEFAULTS | ) | throw (CORBA::SystemException)`[virtual]`

| sets the public key to be used for encryption of the data.

void TAO_FlowProducer::set_source_id | ( | CORBA::Long source_id | ACE_ENV_ARG_DECL_WITH_DEFAULTS | ) | throw (CORBA::SystemException)`[virtual]`

| sets the source id of this flow producer so that it can be used to distinguish this producer from others in the multicast case.

void TAO_FlowProducer::start | ( | ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS |  | ) | throw (CORBA::SystemException)`[virtual]`

| start this flow, to be overridden by the application.

void TAO_FlowProducer::stop | ( | ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS |  | ) | throw (CORBA::SystemException)`[virtual]`

| stop this flow, to be overridden by the application.
