Detailed Description

Class DtAggregateFormationController is a controller that manages the formation state for an aggregate entity.

End User Description: The DtAggregateFormationController manages the state associated with an aggregate entity's formation. This includes determining who is eligible to participate in the formation, and who should be positioned relative to whom when participating in the formation.

It is intended to work in conjunction with the aggregate controllers that model the various movement behaviors (e.g. DtAggregateMoveAlongController, DtAggregatePatrolBetweenController). The DtAggregateFormationController sets formation state (keeping it up to date), and the movement controllers examine the formation state and use that information to execute movement in formation.

This controller may only be configured as a part of an entity that has a vrf-aggregate-state-repository.

Developer Description: The DtAggregateFormationController class handles all DtSetDataRequests that affect formation, including DtSetLocationRequests, DtSetHeadingRequests, and DtSnapIntoFormationRequests. It sets the state in the aggregate entity's DtFormationState object (owned by the DtVrfAggregateStateRepository class). Therefore it should only be configured as part of an aggregate entity that has a DtVrfAggregateStateRepository.

Uses Descriptor Type: DtFormationControllerDescriptor

The ID of the entity whose subordinates have changed (ID of the aggregate).

virtual void DtDisaggregatedFormationController::snapIntoFormation ( const DtString &  formation, const DtVector &  location, double  heading, bool  applyHeading  )

protectedvirtual

Puts the aggregate into the given formation, at the given location and heading.

Issues set data request messages to each subordinate in the aggregate. Computes the position for each subordinate needed to construct the formation at the given location and heading. For individual subordinates, issues DtSetLocationRequests and DtSetHeadingRequests at the computed location and given heading. If applyFormationToSubaggregates is true (recurse), then for aggregate subordinates, issues DtSnapIntoFormationRequests at the computed location and given heading, thereby recursively snapping the aggregate into formation. Otherwise (applyFormationToSubordinates is false, no recursion) issues DtSetLocationRequest and DtSetHeadingReuqest to aggregate subordinates in the same way as for individuals. This allows for mixed formation (don't recursively apply given formation to subordinate aggregates).

Parameters

formation	Type of formation to snap into.
location	Local position aggregate where aggregate should position itself in formation.
heading	Heading in radians at which aggregate should position itself in formation.

virtual void DtDisaggregatedFormationController::getCurrentFormation ( DtFormation &  formation )

protectedvirtual

Get current formation position and formation type.

If aggregate has a working formation, returns the current ad hoc formation positions from the process state repository. Otherwise, looks up known type of formation (e.g. column, line, wedge), return the formation from the formation descriptor.

Parameters

formation

Type of formation (see extendedAggregateEnums.h for list of available types).

virtual DtOrgViewManagedObjectListConstPtr DtDisaggregatedFormationController::generateListOfSubordinatesEligibleForFormation ( )

protectedvirtual

Generates the subset of subordinates available to participate in formation.

Only subordinates that are alive and not independently tasked are included in the result.

Returns

The list of subordinates able to participate in formation. (mySubordinateInFormation)

virtual std::list<int> DtDisaggregatedFormationController::generateFormationPositions ( DtOrgViewManagedObjectListConstPtr &  entityInFormation )

protectedvirtual

Generates a list of formation positions for each entity in the formation.

If auto-promote-in-formation is false, positions are skipped in the formation for any entities that that have left the formation or are destroyed. Otherwise, the first n positions in the formation are used, based on the number of entities to be placed into formation.

virtual int DtDisaggregatedFormationController::findPositionInVector ( const std::vector< DtEntityIdentifier >  subordinateList, const DtEntityIdentifier &  entityId  ) const

protectedvirtual

Helper function for generateFormationPositions().

Returns

The position of entityId in the vector subordinateList.

virtual void DtDisaggregatedFormationController::generateFormationAtPositionAndOrientation ( const DtVector &  geocentricOrigin, const DtTaitBryan &  geocentricOrientation, std::vector< DtVector >  geocentricPositions, DtFormation &  formation  )

protectedvirtual

Constructs an ad hoc formation (set of positional offsets of participants) based on current relative positioning of subordinates, at given location and orientation.

Parameters

geocentricOrigin	Origin of coordinate system in geocentric coordinates, in which relative formation positions are computed from geocentric subordinate positions.
geocentricOrientation	Orientation of coordinate system in geocentric coordinates, to be used to compute formation positions from subordinate positions.
formation	constructed from relative subordinate positions.

virtual void DtDisaggregatedFormationController::generateWorkingFormation ( DtFormation &  formation )

protectedvirtual

Creates an ad hoc formation from the current eligible subordinates current positions relative to one another.

Parameters

formation

The generated formation.

virtual void DtDisaggregatedFormationController::updateFormationState ( )

protectedvirtual

Recomputes and updates current working formation in process state repository, and updates subordinate list and formation positional data.

virtual void DtDisaggregatedFormationController::registerWithOrgManager ( )

protectedvirtual

Register subordinateOrderChangedCallback with the DtOrganizationManager.

virtual void DtDisaggregatedFormationController::unregisterWithOrgManager ( )

protectedvirtual

Unregister subordinateOrderChangedCallback with the DtOrganizationManager.

virtual void DtDisaggregatedFormationController::sendRequestToSelf ( const DtSetDataRequest &  request ) const

protectedvirtual

Send given request to ourself.

Fills out data request message and sends it through the aggregate's radio.

Parameters

request

A set data request to be issued to ourself.

virtual void DtDisaggregatedFormationController::sendRequestToSubordinate ( const DtSetDataRequest &  request, const DtString &  subordinateObjectName  ) const

protectedvirtual

Send given request to one of our subordinates.

Fills out data request message and sends it to subordinate through our entity's radio.

Parameters

request	The data request to send to the given subordinate.
subordinateObjectName	The object name of the subordinate to be given the set data request.

virtual bool DtDisaggregatedFormationController::createPSR ( )

protectedvirtual

Creates myProcessState data member, and adds it to our process state repository manager.

Passes in the name and type specified in the component descriptor (if they exist) to the DtVrfProcessStateRepository::createRepository factory method. If name and/or type is not specified, uses the appropriate default strings defined in procSRTypes.h.

virtual void DtDisaggregatedFormationController::processOnTaskNotifyCallback ( const DtSimTask &  task, const DtSimComponent &  notifier  )

protectedvirtual

Called when the entity is about to start a new task.

Checks to see if any subordinates need to be re-added into the formation This can occur when a subordinate is independently tasked, but is later set to be tasked by superior again. 'Rediscover' these subordinates and bring them back into the formation.

Parameters

task	Task aggregate is about to start.
notifier	Component responsible for executing task.

static void DtDisaggregatedFormationController::requestAvailableFormationsCallback ( const DtVrfObjectMessage *  msg, void *  usr  )

staticprotected

virtual void DtDisaggregatedFormationController::processRequestAvailableFormations ( const DtVrfObjectMessage *  msg )

protectedvirtual

virtual void DtDisaggregatedFormationController::addSetDataCallbacks ( )

protectedvirtual

Add set data request callbacks.

Set data request callbacks are added when component is first created, and whenever component is enabled.

Reimplemented in DtDisaggregatedConvoyFormationController.

void DtDisaggregatedFormationController::removeSetDataCallbacks ( )

protected

Callbacks are removed when component is disabled or destroyed.

Non-virtual because it is called from the destructor.

Reimplemented in DtDisaggregatedConvoyFormationController.
