Member Function Documentation

virtual void DtRemoteComponentAttachmentManager::addRecentArrival ( DtVrfObject *  pVrfObj )

virtual

adds the global object designator to the list of recent arrivals

virtual void DtRemoteComponentAttachmentManager::attach ( const DtRemoteConfigurationMapEntry &  entry, DtVrfObject &  obj  )

virtual

Arrange for component attachment through pMyRemoteConfigBuilder.

virtual bool DtRemoteComponentAttachmentManager::isRemoteComponentAttachment ( const DtUUID &  ) const

virtual

Returns true if the object is a remote component that is attached.

virtual DtRemoteConfigurationMapper* DtRemoteComponentAttachmentManager::attachmentRules ( )

virtual

Return myAttachmentList, a list of attachment rules.

virtual const DtRemoteConfigurationMapper* DtRemoteComponentAttachmentManager::attachmentRules ( ) const

virtual

DtRemoteComponentConfigurationBuilder::CreatorFcn DtRemoteComponentAttachmentManager::builderCreatorFcn ( )

inline

Get/Set the DtRemoteComponentConfigurationBuilder factory function.

References myRemoteConfigBuilderCreatorFcn.

void DtRemoteComponentAttachmentManager::setBuilderCreatorFcn ( DtRemoteComponentConfigurationBuilder::CreatorFcn  fcn )

inline

References myRemoteConfigBuilderCreatorFcn.

virtual void DtRemoteComponentAttachmentManager::clear ( )

virtual

Purge all lists, return memory to the heap.

This also calls clearRecentArrivals();

virtual DtRemoteConfigurationMapper* DtRemoteComponentAttachmentManager::createAttachmentRules ( const char *  pReaderWriterName )

virtual

Create pMyAttachmentRules, override to instantiate derived type.

Example name: "remote-configurations" This does not set pMyAttachmentRules. Rather this is called from initialize(), and initialize() assigns the results to pMyAttachmentRules. createAttachmentRules() will only be called if pMyAttachmentRules is NULL.

virtual void DtRemoteComponentAttachmentManager::clearRecentArrivals ( )

virtual

Empty the recent arrivals list.

virtual EvaluationReadinessState DtRemoteComponentAttachmentManager::checkReadinessCriteria ( DtVrfObject &  obj )

virtual

Inspect the the given object, determine if it's ready to be evaluated for attachment.

Returns: Remove - this object shouldn't be evaluated, and should be removed. NotReady - there isn't enough information for evaluation. true - the object is ready to be evaluated for remote component attachment.

virtual bool DtRemoteComponentAttachmentManager::checkRejectionCriteria ( DtVrfObject &  obj )

virtual

Inspect the given object, and perform exclusion checks to eliminate the object from consideration.

This is called at the beginning of checkReadinessCriteria(). The base class rejects objects that are local to the simulation, and objects that are simulated by VR-Forces. Returns true to signal reject. Returns false to accept object for further evaluation.

virtual void DtRemoteComponentAttachmentManager::destroyAttachmentRules ( )

virtual

Calls clear(), deletes pMyAttachmentRules, sets to NULL.

virtual void DtRemoteComponentAttachmentManager::evaluateAndAttach ( DtVrfObject &  obj )

virtual

Examine if remote component attachment should take place, and call attach().

The evaluation order is: entity identifier, marking text, object type.

virtual bool DtRemoteComponentAttachmentManager::initialize ( const DtFilename &  fromFile )

virtual

Purge the remote component attachment system, then reinitialize from the file.

virtual void DtRemoteComponentAttachmentManager::processRemoveFromArrivals ( DtVrfObject *  pVrfObj )

virtual

Removes this object from the recent arrivals queue.

virtual void DtRemoteComponentAttachmentManager::processRemoveFromArrivals ( const DtUUID &  )

virtual

virtual void DtRemoteComponentAttachmentManager::resetAllReflectedObjectsToNonVrfSimulated ( )

virtual

For all confirmed attachments, reset VRF-simulated flag.

virtual void DtRemoteComponentAttachmentManager::resetReflectedObjectToNonVrfSimulated ( DtVrfObject *  pVrfObj )

virtual

reset VRF-simulated flag.

virtual void DtRemoteComponentAttachmentManager::tick ( )

virtual

Checks next scheduled tick, call doWork()

DtTime DtRemoteComponentAttachmentManager::tickRate ( ) const

inline

Get/Set the tick interval for the attachment manager.

References myTickRate.

void DtRemoteComponentAttachmentManager::setTickRate ( DtTime  interval )

inline

References myTickRate.

DtVrfObjectManager * DtRemoteComponentAttachmentManager::vrfObjectManager ( )

inline

Get/Set the tick interval for the attachment manager.

References pMyObjMgr.

const DtVrfObjectManager * DtRemoteComponentAttachmentManager::vrfObjectManager ( ) const

inline

References pMyObjMgr.

virtual void DtRemoteComponentAttachmentManager::processVrfObjectToBeRemoved ( DtVrfObject *  pVrfObject )

virtual

Reset the reflected object back to non-vrf simulated, if it is listed in myConfirmedAttachments.

static void DtRemoteComponentAttachmentManager::vrfObjectToBeRemovedCallback ( DtVrfObject *  pVrfObject, void *  pUsr  )

static

Registered with DtVrfObjectManager::addSimObjectAboutToBeRemovedCallback() to reset the reflected object back to non-vrf simulated.

virtual void DtRemoteComponentAttachmentManager::doWork ( )

protectedvirtual

Walk the recent arrivals list, evaluating members against eligibility for attachment.

Called by tick() in order to do work. Override doWork() to extend or override the base class behavior.

const DtRemoteComponentAttachmentManager& DtRemoteComponentAttachmentManager::operator= ( const DtRemoteComponentAttachmentManager &  )

Member Data Documentation

RecentArrivalsMap DtRemoteComponentAttachmentManager::myConfirmedAttachments

protected

keep track of what entities contain attachments

DtTime DtRemoteComponentAttachmentManager::myNextTick

protected

Next scheduled tick time.

RecentArrivalsMap DtRemoteComponentAttachmentManager::myRecentArrivals

protected

This list captures the IDs of newly discovered simulated things.

DtRemoteComponentConfigurationBuilder* DtRemoteComponentAttachmentManager::pMyRemoteConfigBuilder

protected

This helps parse configuration files and add components to remote entities.

The remote builder is used when objects are discovered, and an attachment entry exists for the object in pMyAttachmentRules. Call "setBuilderCreatorFcn()" to cause the Remote Attachment Manager to use a different kind of builder. DtMtlRemoteComponentConfigurationBuilder is use by default.

DtRemoteComponentConfigurationBuilder::CreatorFcn DtRemoteComponentAttachmentManager::myRemoteConfigBuilderCreatorFcn

protected

This creator function is used by initialize() to create pMyRemoteConfigBuilder.

By default, it is set to use DtMtlRemoteComponentConfigurationBuilder

Referenced by builderCreatorFcn(), and setBuilderCreatorFcn().

DtRwUUID DtRemoteComponentAttachmentManager::myWorkerKey

protected

This is a worker key, to facilitate searching without requiring allocations.

DtTime DtRemoteComponentAttachmentManager::myTickRate

protected

Tick Rate, default 5.0 secs.

Referenced by setTickRate(), and tickRate().

DtVrfObjectManager* DtRemoteComponentAttachmentManager::pMyObjMgr

protected

This is a pointer to the singleton's parent object.

Referenced by vrfObjectManager().

DtRemoteConfigurationMapper* DtRemoteComponentAttachmentManager::pMyAttachmentRules

protected

The attachment list is a container of attachment rules.
