LazyGoal

open class LazyGoal<T>(coroutineContext: CoroutineContext = EmptyCoroutineContext, val dependencies: Collection<Goal<*>> = emptyList(), val block: suspend () -> T) : Goal<T>

Parameters

coroutineContext

additional context information

Constructors

LazyGoal

constructor(coroutineContext: CoroutineContext = EmptyCoroutineContext, dependencies: Collection<Goal<*>> = emptyList(), block: suspend () -> T)

Properties

block

val block: suspend () -> T

deferred

override var deferred: Deferred<T>?

Returns current running coroutine if the goal is started. Null if the computation is not started.

dependencies

open override val dependencies: Collection<Goal<*>>

isComplete

val Goal<*>.isComplete: Boolean

Functions

async

open override fun async(coroutineScope: CoroutineScope): Deferred<T>

Get ongoing computation or start a new one. Does not guarantee thread safety. In case of multi-thread access, could create orphan computations. If GoalExecutionRestriction is present in the coroutineScope context, the call could produce a error a warning depending on the settings.

await

suspend fun <T> Goal<T>.await(): T

launch

fun Goal<*>.launch(coroutineScope: CoroutineScope): Job

reset

open override fun reset()

Reset the computation
