protected

assignment operator

virtual void DtUnknownHlaObject::reflect ( const DtStateMsg &  stateMsg )

protectedvirtual

Does nothing.

You can access information from incoming update messages by using DtHlaObject::addPostReflectCb to register a function that will be called whenever an update msg is received.

Implements DtHlaObject.

virtual bool DtUnknownHlaObject::update ( )

virtual

Does nothing.

Use the version of update that takes an ahpvs to send data for a DtUnknownHlaObject. Will return true if data sent.

Reimplemented from DtHlaObject.

virtual bool DtUnknownHlaObject::update ( const RTI::AttributeHandleValuePairSet &  ahvps )

virtual

Sends the ahpvs through our DtExerciseConn.

Does not look at the contents of ahvps. It is the caller's responsibility to insure that all attributes in the message are in the set of attributes needed by the federation (obtained using attributesNeededByFederation). It is also the responsibility of the user of DtUnknownHlaObject to insure that requested attributes (obtained via requestedAttributes) get updated in a timely manner. clearRequestedAttributes should be called after each time requested attributes are updated. Will return true if data sent.
