DART隔离和线程（Java，C＃）之间的区别 [英] Difference between DART Isolate and Thread (Java,C#)

问题描述

对我来说，DART隔离看上去像是具有不同术语的线程（Java / C＃）。

For me The DART Isolate looks like a Thread (Java/C#) with a different terminology. In which aspect Isolate differs from a Thread?

推荐答案

线程使用共享内存，而隔离对象则没有。

Threads use shared memory, isolates don't.

例如，以下伪代码（在Java / C＃中）

For example, the following pseudocode in Java/C#

class MyClass {
  static int count = 0;
}

// Thread 1: 
MyClass.count++;
print(MyClass.count); // 1;

// Thread 2:
MyClass.count++;
print(MyClass.count); // 2;

这也存在两个线程同时修改共享内存的风险。

This also runs the risk of the shared memory being modified simultaneously by both threads.

在Dart中，

class MyClass {
  static int count = 0;
}

// Isolate 1: 
MyClass.count++;
print(MyClass.count); // 1;

// Isolate 2:
MyClass.count++;
print(MyClass.count); // 1;

隔离是彼此隔离的。它们之间进行通信的唯一方法是传递消息。一个隔离器可以侦听来自另一个隔离器的回调。

Isolates are isolated from each other. The only way to communicate between them is to pass messages. One isolate can listen for callbacks from the other.
