    this.getstate

    线程类Thread.State getState() (Thread Class Thread.State getState())

    • This method is available in package java.lang.Thread.getState().

      软件包java.lang.Thread.getState()中提供了此方法。

    • This method is used to return the state of this thread.

      此方法用于返回此线程的状态。

    • When we execute a thread so there are various states for normal execution of the thread [States of the Thread like, start, ready, running, waiting, blocked, terminate].

      当我们执行一个线程时,有多种状态可以正常执行该线程[线程的状态,如启动,就绪,运行,等待,阻塞,终止]。

    • This method is not final so we can override this method in child class.

      此方法不是最终方法,因此我们可以在子类中重写此方法。

    • The return type of this method is Thread.State so it returns the state of this thread

      此方法的返回类型为Thread.State,因此它返回此线程的状态。

    • This method does not raise any exception.

      此方法不会引发任何异常。

    Syntax:

    句法:

        Thread.State getState(){
        }
    
    

    Parameter(s):

    参数:

    We don't pass any object as a parameter in the method of the Thread.

    我们不会在Thread方法中将任何对象作为参数传递。

    Return value:

    返回值:

    The return type of this method is Thread.State, it returns the state of this thread.

    该方法的返回类型为Thread.State ,它返回此线程的状态。

    Java程序演示getState()方法的示例 (Java program to demonstrate example of getState() method)

    /*  We will use Thread class methods so we are importing 
        the package but it is not mandate because 
        it is imported by default
    */
    
    import java.lang.Thread;
    
    class GetThreadState extends Thread {
        // Override run() of Thread class
        public void run() {
            // By using getState() method is used to return 
            // the state of this thread
            System.out.println("The state of this thread is : " + Thread.currentThread().getState());
    
            /* This is another way of writing the above statement
            Thread.State th_state = Thread.currentThread().getState();
            System.out.println("The state of this thread is : "+th_state);*/
        }
    
        public static void main(String[] args) {
            // Creating an object of GetThreadState class
            GetThreadState gt_state = new GetThreadState();
    
            // We are setting the name of the thread GetThreadState
            gt_state.setName("GetThreadState");
    
            // Calling start() method with GetThreadState class 
            // object of Thread class/
            gt_state.start();
    
            // By using getName() method to return the name of this 
            // thread [GetThreadState]
            System.out.println("The name of this thread is " + " " + gt_state.getName());
        }
    }

    一、获取数据store.getState()
    在这里插入图片描述
    src/store/index.js

    import { createStore } from 'redux'  //  引入方法
    import reducer from './reducer'    
    const store = createStore(reducer) // 创建数据存储仓库
    export default store   
    

    src/store/reducer.js

    const defaultState = {
        inputValue : 'hello world'
    }
    function fn(state = defaultState,action){
            return state
    }
    const state=fn
    export default state
    

    组件使用:
    src/views/a.js

    import React from 'react'
    import store from '../store/index' 
    class A extends React.Component {
    constructor(props){ 
      super(props)
      this.state=store.getState();
    }
    render() {
        return (
          <div >
              a页面
    		{this.state.inputValue}
          </div >
        )
      }
    }
    export default A
    

    二、修改数据 store.dispatch(action)

          console.log(newRouter)
          dispatch({ type: 'SET_LIGHT_STATE', key: ['router'], value: newRouter })
        }
      })
