virtual ReturnCode_t RTC::InPortBase::notify_connect	(	ConnectorProfile &	connector_profile	)
throw	(	CORBA::SystemException
	)

virtual

[CORBA interface] Notify the Ports connection

This operation is usually called from other ports' connect() or notify_connect() operations when connection between ports is established. This function is not premised on calling from other functions or application programs.

According to the template method pattern, the notify_connect() calls "publishInterfaces()" and "subsctiveInterfaces()" functions, which are premised on implementing in the subclasses. The processing sequence is as follows.

publishInterfaces(): Publishing interface information
connectNext(): Calling notify_connect() of the next port
subscribeInterfaces(): Subscribing interface information
Storing connection profile

According to the order of port's references stored in the ConnectorProfile::ports, publishing interface information to all the ports and subscription interface information from all the ports is performed by "notify_connect()"s. This cascaded call never aborts in the halfway operations, and calling sequence shall be completed for all the ports.

Precondition: notify_connect() calls notify_connect() for the port's reference that is stored in next of this port's reference in the sequence of the ConnectorProfile::ports. Therefore the reference of this port shall be stored in the ConnectorProfile::ports. If this port's reference is not stored in the sequence, BAD_PARAMETER error will be returned, except the return code is overwritten by other operations.; UUID shall be set to ConnectorProfile::connector_id as a unique identifier when this operation is called. Usually, connector_id is given by a connect() function and, the behavior is undefined in the case of a null character.

Postcondition: ConnectorProfile::name, ConnectorProfile::connector_id, ConnectorProfile::ports are invariant, and they are never rewritten by notify_connect() operations.; In order to transfer interface information to other ports, interface property information is stored into the ConnectorProfile::properties.; At the end of notify_connect() operation for the first port stored in the ConnectorProfile::ports sequence, the related ports' notify_connect() invocations complete. Even if errors are raised at the halfway of publishInterfaces(), connectNext(), subscribeInterfaces() and storing process of ConnectorProfile, error codes are saved and the first error is returned.

Parameters

connector_profile The ConnectorProfile.

Returns: ReturnCode_t The return code of ReturnCode_t type.

Reimplemented from RTC::PortBase.

coil::Properties& RTC::InPortBase::properties ( )

Get properties.

This method gets properties in the port.

Returns: Properties

virtual ReturnCode_t RTC::InPortBase::publishInterfaces ( ConnectorProfile & connector_profile )

protectedvirtual
