一套前端设计语言和基于React的实现

import { PureComponent } from 'react';
import { WaypointPosition } from './position';
export interface IWaypointCallbackData {
    currentPosition: WaypointPosition;
    previousPosition: WaypointPosition;
    event: Event | null;
    waypointTop: number;
    waypointBottom: number;
    viewportTop: number;
    viewportBottom: number;
}
export interface IWaypointProps {
    scrollableAncestor?: HTMLElement | Window;
    children?: React.ReactNode;
    topOffset?: number | string;
    bottomOffset?: number | string;
    horizontal?: boolean;
    fireOnRapidScroll?: boolean;
    onEnter?: (data: IWaypointCallbackData) => void;
    onLeave?: (data: IWaypointCallbackData) => void;
    onPositionChange?: (data: IWaypointCallbackData) => void;
}
export declare class Waypoint extends PureComponent<IWaypointProps> {
    static defaultProps: {
        topOffset: number;
        bottomOffset: number;
        horizontal: boolean;
        fireOnRapidScroll: boolean;
    };
    private refElement;
    private cancelOnNextTick;
    private scrollEventListenerUnsubscribe;
    private resizeEventListenerUnsubscribe;
    private scrollableAncestor;
    private previousPosition;
    componentDidMount(): void;
    componentDidUpdate(): void;
    componentWillUnmount(): void;
    private findScrollableAncestor;
    private handleScroll;
    private getBounds;
    private getOffset;
    render(): JSX.Element;
