ohos.aafwk.ability.fraction.Fraction

所有已实现的接口:

ILifecycle, Context

public class Fraction
extends AbilityContext
implements ILifecycle

Provides lifecycle callbacks of a fraction.

A Fraction can be placed in a container (an Ability) as a part of its UI and cannot be used independently. The lifecycle state of a Fraction depends on its container. If the container is destroyed, all fractions in it will also be destroyed. You can use the Fraction to define a variety of layouts to enrich the user interface of your application.
