AbstractReaction

abstract class AbstractReaction<T>(initialOccurrence: Time) : Reaction<T>

Owner-neutral implementation of the reactive state shared by all Reactions.

Parameters

initialOccurrence

the occurrence exposed before engine initialization

Type Parameters

T

concentration type

Inheritors

AbstractNodeReaction

Constructors

AbstractReaction

constructor(initialOccurrence: Time)

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.

abstract val host: ReactionHost<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.

override val nextOccurrence: Observable<Time>

The absolute Time of the next occurrence.

Functions

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<*>)

toGraphQLReactionSurrogate

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

Converts a node-hosted Reaction to a ReactionSurrogate.

open override fun toString(): String

updateSchedulingAfterInvalidation

override fun updateSchedulingAfterInvalidation(currentTime: Time)

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