Classes

ComputedNode<T>: A reactive computed node that derives its value from other reactive nodes.
EffectNode<T>: A reactive effect node that runs side effects in response to changes.
EffectScopeNode: A reactive effect scope node that can participate in propagation.
LinkedEffect: A reactive node that can be linked in a queue of effects.
PresetReactiveSystem: Default implementation of the reactive system for Alien Signals.
SignalNode<T>: A reactive signal node that holds a value of type T.

activeSub ↔ ReactiveNode?: The currently active subscriber node.
getter/setter pair
batchDepth ↔ int: Current depth of nested batch operations.
getter/setter pair
checkDirty → bool Function(Link link, ReactiveNode sub): final
cycle ↔ int: Global version counter for tracking dependency updates.
getter/setter pair
link → void Function(ReactiveNode dep, ReactiveNode sub, int version): final
propagate → void Function(Link link, [bool innerWrite = false]): final
queuedEffects ↔ LinkedEffect?: Head of the queue of effects waiting to be executed.
getter/setter pair
queuedEffectsTail ↔ LinkedEffect?: Tail of the effects queue for O(1) append operations.
getter/setter pair
runDepth ↔ int: Current depth of nested effect callback execution.
getter/setter pair
shallowPropagate → void Function(Link link): final
unlink → Link? Function(Link link, ReactiveNode sub): final

disposeAllDepsInReverse(ReactiveNode sub) → void: Removes every dependency from sub, starting from the newest link.
disposeChildDepsInReverse(ReactiveNode sub) → void: Disposes child effects/scopes while leaving signal/computed deps for purge.
endBatch() → void: Ends the current batch operation.
flush() → void: Flushes all queued effects, executing them in order.
getActiveSub() → ReactiveNode?: Gets the currently active subscriber node.
getBatchDepth() → int: Gets the current batch depth.
purgeDeps(ReactiveNode sub) → void: Removes all stale dependencies from a subscriber node.
run(EffectNode e) → void: Executes an effect node if it needs updating.
runCleanup(EffectNode e) → void: Runs an effect cleanup outside dependency tracking.
setActiveSub([ReactiveNode? sub]) → ReactiveNode?: Sets the active subscriber node and returns the previous one.
startBatch() → void: Starts a new batch operation.
stop(ReactiveNode node) → void: Stops a reactive node and removes it from the reactive system.
stopEffect(EffectNode e) → void: Stops an effect after disposing its nested effects and scopes.
stopScope(ReactiveNode node) → void: Stops a scope-like node and disposes all dependencies in reverse order.
trigger(void fn()) → void: Manually triggers reactive updates within a function.

EffectCallback<T> = T Function(): Callback passed to an effect.
EffectCleanup = void Function(): Cleanup function returned by an effect callback.
