Properties

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

The list of Actions of the Reaction. Please be careful when you modify this list.

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

The list of Conditions of the Reaction. Please be careful when you modify this list.

inboundDependencies

val inboundDependencies: ListSet<Dependency?>

val inputContext: Context

The widest Context among Conditions, namely the smallest Context in which the Reaction can read informations.

val node: Node<T?>

outboundDependencies

val outboundDependencies: ListSet<Dependency?>

val outputContext: Context

The widest Context among Actions, namely the smallest context in which the Reaction can do modifications.

open val rate: Double

Returns the speed of this Reaction. It is an average number, and can potentially change during the simulation, depending on the implementation.

open val steerStrategy: SteeringStrategy<T, Euclidean2DPosition>

the strategy used to combine steering actions

timeDistribution

val timeDistribution: TimeDistribution<T?>

Functions

open fun canExecute(): Boolean

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

This method allows to clone this reaction on a new node. It may result useful to support runtime creation of nodes with the same reaction programming, e.g. for morphogenesis.

operator fun compareTo(o: Actionable<T?>): Int

open override fun execute()

Executes the reactions.

initializationComplete

open fun initializationComplete(@Nonnull atTime: Time, @Nonnull environment: Environment<T?, *>)

This method is called when the environment has completed its initialization. Can be used by this reaction to compute its next execution time - in case such computation requires an inspection of the environment.

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

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

The list of steering actions in this reaction.

toGraphQLReactionSurrogate

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

Converts a Reaction to a ReactionSurrogate.

fun update(@Nonnull currentTime: Time, hasBeenExecuted: Boolean, @Nonnull environment: Environment<T?, *>)

Updates the scheduling of this reaction.
