Detailed Description

Instances of DtObjectPublisher are used for local or source simulations of objects, (i.e.

these objects are not dependent on data being produced elsewhere on the network for their existence). These object send data to the network.

Member Typedef Documentation

typedef DtAttributePdu*(* DtObjectPublisher::DtNonCoupledAttributePduCreator)(const DtPduWithAttributeRecordSets *, void *)

Function prototype for functions that create DtAggregateStateRepositories.

Constructor & Destructor Documentation

DtObjectPublisher::DtObjectPublisher	(	DtExerciseConn *	conn,
		DtStateRepository *	stateRep,
		DtStateRepository *	asSeenByRemote,
		bool	okToDeleteStateRep = true
	)

Constructor takes an DtExerciseConn which must have a lifetime greater than the ObjectPubliser.

It also takes two DtStateRepositories, the stateRep which it destroys in the DTOR if the okToDeleteStateRep flag was set to true, and the asSeenByRemote which is destroyed in the dtor every time.

virtual DtObjectPublisher::~DtObjectPublisher ( )

virtual

Destructor.

DtObjectPublisher::DtObjectPublisher ( const DtObjectPublisher &  orig )

private

copy constructor – not implemented
