We know from before that each variable name belongs to a certain abstract environment or namespace,and we can think of it as a context in which a given name exists. 我们从前面就知道,每个变量名都属于某个抽象环境或名称空间,我们可以将其视为
LifecycleEventObserver{init{// in case we are initialized on a non-main thread, make a best effort check before// we return the scope. This is not sync but if developer is launching on a non-main// dispatcher, they cannot be 100% sure...

: error("Scope cannot be cancelled because it does not have a job: $this") job.cancel(cause) } 1. 2. 3. 4. 它内部先获取CoroutineContext的Job,然后第哦啊有Job的cancel方法,实现协程的取消。我们手动创建的CoroutineScope的CoroutineContext中都是有Job的,例如: val scope = CoroutineScope(Job() +...
Therefore, it can be easily argued that the triple constraint might be the single most important concept in the history of project management. When used in combination with effectiveproject management software, it can give you the ability to drive your projects to success. ...
软件:从开源项目对外输出的制品评估其价值最终落脚点。也是开源评估最“古老”的主流方向之一“开源软件” 的具体表现。 3. 评估模型 基于“开源生态”与“协作、人、软件”的维度,找到与该目标直接或间接相关的可量化指标,对开源项目健康与生态进行量化评估,最终形成开源评估指数。
public fun CoroutineContext.cancel(): Unit { this[Job]?.cancel() } 所以真正的逻辑是从CoroutineContex集合中取出Key为Job的实例,这个对应的就是上面创建LifecycleCoroutineScopeImpl实例时传入的SupervisorJob,它是CoroutineContext的其中一个子类。 这时再来看lifecycleScope相关的一些方法 lifecycleScope.launchWhenCrea...
