abstract class SpecGeneratedComponent : Component, ContentAllocator<Content> , HasEventDispatcher, EventDispatcher, EventTriggerTarget, HasEventTrigger

Base class for all component generated via the Spec API (@LayoutSpec and @MountSpec).

Inheritors

Types

TransitionContainer

interface TransitionContainer

Generated component's state container could implement this interface along with when componentspec specifies state update method with annotation.
