Detailed Description

Instances of DtReflectedEntityList are used to manage remote entities from the network.

DtReflectedEntityList, when instantiated, subscribes to all of the classes either specified by the FOM Mapper used by the DtExerciseConn or provided in the form of Object Class Handles. When an object of type handled by DtReflectedEntityList is discovered, a DtReflectedEntity is created and added to the list. DtReflectedEntityList provides a mechanism to maintain the list of remote entities and their data. In addition, DtReflectedEntityList provides callback mechanisms that the user may register for, so that the user may be notified and do certain processing when an entity is added/removed from the reflected entity list.

Examples

virtual void DtReflectedEntityList::entityAdded ( DtReflectedEntity * ent )

protectedvirtual

Called by objectAdded (which is called from processDiscoverObject()) after a remote entity has been added to the list.
