PrioritySteering

class PrioritySteering<T>(environment: Euclidean2DEnvironment<T>, pedestrian: PedestrianProperty<T>, timeDistribution: TimeDistribution<T>) : SteeringBehavior<T>

Steering behavior that executes only the steering action targeting the nearest destination.

Parameters

environment

the environment in which the pedestrian moves.

timeDistribution

the time distribution governing reaction execution.

Type Parameters

T

the concentration type.

Constructors

PrioritySteering

constructor(environment: Euclidean2DEnvironment<T>, pedestrian: PedestrianProperty<T>, timeDistribution: TimeDistribution<T>)

Properties

open override var actions: List<Action<T>>

The Actions executed by this reaction.

open override val canExecute: Observable<Boolean>

Observes whether the reaction procedure can be selected and executed by the engine. This observable emits updates when that state changes. Reactions whose procedure includes checking occurrence-time conditions may remain executable even when those conditions will suppress their model effects.

open override var conditions: List<Condition<T>>

The Conditions interpreted by this reaction's scheduling and execution policy.

finitePositiveMeanDelayOrError

open val finitePositiveMeanDelayOrError: Double

The current meanDelay, for consumers requiring it to be finite and positive, such as those converting speeds into per-occurrence movements.

override val host: Node<T>

The model entity hosting this reaction, fixed for the lifetime of the reaction. A host only registers reactions whose host is the host itself.

open override val meanDelay: Double

The expected delay between two occurrences of this reaction in the current model state.

override val nextOccurrence: Observable<Time>

The absolute Time of the next occurrence.

open val steerStrategy: SteeringStrategy<T, Euclidean2DPosition>

the strategy used to combine steering actions

timeDistribution

override val timeDistribution: TimeDistribution<T>

The delay distribution governing this reaction's putative occurrences.

Functions

open override fun cloneOnNewNode(node: Node<T>): SteeringBehavior<T>

Clones this reaction's program on a new node, for example when nodes are created at runtime.

operator override fun compareTo(other: Reaction<T>): Int

open override fun dispose()

Disposes and releases the resources held by this object.

open override fun execute()

Prepares valid conditions, applies the model mutation, and advances surviving distributed reactions.

initializationComplete

override fun initializationComplete(atTime: Time, environment: Environment<T, *>)

Initializes reactive inputs after the model has been fully assembled.

infix fun Reaction<*>.shouldEqual(other: Reaction<*>)

fun steerActions(): List<SteeringAction<T, Euclidean2DPosition>>

The list of steering actions in this reaction.

toGraphQLReactionSurrogate

fun <T> NodeReaction<T>.toGraphQLReactionSurrogate(): ReactionSurrogate<T>

Converts a NodeReaction to a ReactionSurrogate.

fun <T> Reaction<T>.toGraphQLReactionSurrogate(host: Node<T>): ReactionSurrogate<T>

Converts a node-hosted Reaction to a ReactionSurrogate.

open override fun toString(): String

updateSchedulingAfterFiring

override fun updateSchedulingAfterFiring(currentTime: Time)

Refreshes reaction state after firing, then applies firing scheduling policy.

updateSchedulingAfterInvalidation

override fun updateSchedulingAfterInvalidation(currentTime: Time)

Refreshes this reaction's scheduling after one or more observed model inputs changed.
