reactjs - 在reactjs中，wrappedComponent.propTypes是什么？

Question

下面的代码示例是组件的简化版本。我不明白该组件底部的代码，即 Case.wrappedComponent.propTypes 部分。我在互联网上也找不到有关wrappedComponent的相关文档。

问题:

1. 里面的wrappedComponent和propTypes键是什么？
2. 他们做什么？

3. 在哪里可以找到这些内容的文档？

   import React, { Component } from 'react';
   
   @inject('store') @observer
   export default class Case extends Component {
   
     constructor(props) {
     super(props);
   
     this.caseId = this.props.match.params.id;
   
   
     this.setOtherComment = this.setOtherComment.bind(this)
     this.submitOtherComment = this.submitOtherComment.bind(this)
     }
   
   
   
     render() {
       return '...'
     }
   }
   
   Case.wrappedComponent.propTypes = {
     store: React.PropTypes.object.isRequired,
     match: React.PropTypes.object.isRequired
   };

这是 mobx-react 的 API(带注入(inject))，根据 DOCS

Using propTypes and defaultProps and other static properties in combination with inject Inject wraps a new component around the component you pass into it. This means that assigning a static property to the resulting component, will be applied to the HoC, and not to the original component

........

if you want to make assertions on the data that is being injected (either stores or data resulting from a mapper function), the propTypes should be defined on the wrapped component. Which is available through the static property wrappedComponent on the inject component
