Detailed Description

This controller is part of the traffic spawn system.

It creates new entities at a defined interval and gives them a plan to move toward a random sink object. It then monitors these entities, when when they are close to their sink point, it deletes them.

Member Function Documentation

virtual const char* DtSpawnController::type ( ) const

virtual

This returns a string from compTypes.h, and identifies the type of component.

Implements DtControllerComponent.

static DtSimComponent* DtSpawnController::creator ( const DtString &  name, DtVrfObject *  owner, DtSimManager *  simManager, DtComponentDescriptor *  desc = 0, DtReaderWriterRegistry *  parentRegistry = 0  )

static

(const DtString&,DtVrfObject*,DtSimManager*,

Parameters

name	Reader writer name of this component.
owner	The DtVrfObject that owns this component
simManager	The simulation manager (provides access to terrain, message interface, simulation clock).
desc	The component descriptor used to initialize this component.
parentRegistry	Pointer to the parent reader writer registry (the containing object that reads/writes this object).

(const DtString&,DtVrfObject*,DtSimManager*, DtComponentDescriptor*,DtReaderWriterRegistry* parentRegistry)

Returns

New instance of this class.

const DtString& DtSpawnController::templateName

(

)

const

Provide the template name. For backwards compatability only. Use spawnTemplateUUID for new code.

static void DtSpawnController::settingConsumerCallback ( const DtSettingsObject *  settingsObject, void *  usr  )

static

Initialization functions.

virtual void DtSpawnController::registerTaskMsgCallbacks ( )

virtual

Register a callback for notification of DtUserTask messages.

Overrides this so it can register its interest in DtUserTask* commands

virtual void DtSpawnController::unregisterTaskMsgCallbacks ( )

virtual

Unregister a callback for notification of DtUserTask messages.

This is used if the entity cannot process DtUserTasks

virtual bool DtSpawnController::init ( )

virtual

Calls setRadio()

Reimplemented from DtControllerComponent.

virtual void DtSpawnController::refreshSpawnTemplateData ( )

virtual

virtual void DtSpawnController::processSetting ( const DtBoolSetting *  setting )

protectedvirtual

virtual DtSpawnControllerPSR* DtSpawnController::createPSR ( )

protectedvirtual

virtual DtCollisionDetector* DtSpawnController::createCollisionDetector ( )

protectedvirtual

Creates the collision detector.

static void DtSpawnController::requestSpawnPtDataCallback ( const DtVrfObjectMessage *  msg, void *  usr  )

staticprotected

Callback functions for messages.

virtual void DtSpawnController::preFirstTickInit ( )

virtual

Tick.

The controller must get the pointer to its template at this point; it can't do that in a postScenarioLoad callback function because the spawn-sink manager may not have loaded its templates yet. Also, the init() function is called before postScenarioLoad. See also spawnControllerPSR.h

Reimplemented from DtSimComponent.

virtual void DtSpawnController::tick ( )

virtual

Tick the publisher if the component is on.

Reimplemented from DtSimComponent.

virtual std::list<DtVrfObject*> DtSpawnController::testAndSinkTraffic ( )

protectedvirtual

Check if any of the traffic objects are near their sink points, and delete them if needed.

virtual bool DtSpawnController::shouldSinkObject ( DtVrfObject *  trafficObject, DtVrfObject *  sinkPoint  )

protectedvirtual

Returns

True if trafficObject has met the sink criteria with regard to the specified sink point.

virtual void DtSpawnController::deleteObjects ( const std::list< DtVrfObject * > &  objectList )

protectedvirtual

Deletes the VRF objects contained in this list.

virtual bool DtSpawnController::canCreateNow ( DtTime  timeNow, DtRwSpawnData *  spawnData  ) const

protectedvirtual

Determine if the time parameters permit creation now.

The standard version checks is-time-based, then compares time with start and end times; also checks is-cyclic, and then cycle-period, duty-cycle, and start-offset to determine if the current time is in an active window. The function also checks to see if the current time is past the PSR->nextCycleStartTime(); if so, it computes the start time of the next burst cycle and updates lastCycleStartTime and nextCycleStartTime. All checks assume that the parameters, and the function argument, are in sim time unless isTimeBased and usesClockTime are true.

virtual DtUUID DtSpawnController::findSinkPoint ( )

protectedvirtual

Select a sink point randomly from the list in the template.

virtual DtTime DtSpawnController::nextCreationTime ( DtTime  timeNow, DtRwSpawnData *  spawnData  )

protectedvirtual

Determine the next entity creation time.

The standard version of this method takes the current time, adds period +- variance% x period.

virtual DtVrfObject* DtSpawnController::createObject ( DtVrfObject *  sinkPoint, DtRwSpawnData *  spawnData, DtVrfObject *  objectToRecycle, bool &  dataAvailable  )

protectedvirtual

Create a new traffic object, or recycle an old one into a new one.

virtual DtVector DtSpawnController::creationLocationAndOrientation ( double &  heading, DtVrfObject *  sinkPoint, DtRwSpawnData *  spawnData, bool &  dataAvailable  )

protectedvirtual

Finds the creation location and orientation for a new traffic entity.

virtual void DtSpawnController::createAndSendDefaultPlan ( DtVrfObject *  obj, const DtUUID &  sinkPoint, DtRwSpawnData *  spawnData  )

protectedvirtual

Gives the spawned entity the default plan (move to sink point and delete self) and sends it to the entity.

virtual double DtSpawnController::trafficSpeed ( DtRwSpawnData *  spawnData )

protectedvirtual

Calculates and returns the speed for a new traffic entity.

This will be a random number between min speed and max speed.

virtual void DtSpawnController::sendEntityPlan ( DtVrfObject *  entity, const DtPlan &  plan  )

protectedvirtual

Puts the entityPlan in a message and sends it to the spawned entity.

virtual bool DtSpawnController::trafficObjectType ( DtRwObjectTypeInfo &  objType, DtRwSpawnData *  spawnData  )

protectedvirtual

Provides object type to be used to generate a new traffic entity.

Will be a random object type from the traffic object type list.

Returns

True if found an object type to use.

void DtSpawnController::findClosestRoadSpawnPoints ( )

protected

Find closest points on road network for spawning on roads.

staticprotected

virtual void DtSpawnController::processRefreshSpawnTemplateData ( )

protectedvirtual

virtual bool DtSpawnController::startLocationTaken ( DtVrfObject *  , const DtVector &  geocentricLocation  )

protectedvirtual

Returns true if the start location is taken by a feature or entity and would mean the object could not be placed.

The location is in geocentric

virtual bool DtSpawnController::startLocationTaken ( const DtObjectType &  , const DtVector &  geocentricLocation  )

protectedvirtual

virtual DtRwSpawnData* DtSpawnController::lookupSpawnTemplateData ( )

protectedvirtual

const DtSpawnController& DtSpawnController::operator= ( const DtSpawnController &  orig )

private

assignment operator; not implemented.
