muduo源码的互斥锁源码位于muduo/base,Mutex.h,进行了两个类的封装,在实际的使用中更常使用MutexLockGuard类,因为该类可以在析构函数中自动解锁,避免了某些情况忘记解锁.代码如下所示: // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at c…
muduo库里面的线程池是固定线程池,即创建的线程池里面的线程个数是一定的,不是动态的.线程池里面一般要包含线程队列还有任务队列,外部程序将任务存放到线程池的任务队列中,线程池中的线程队列执行任务,也是一种生产者和消费者模型.muduo库中的线程池源码如下: 线程池头文件ThreadPool.h //线程池 // Use of this source code is governed by a BSD-style license // that can be found in the Licen…
muduo库里面的线程类是使用基于对象的编程思想,源码目录为muduo/base,如下所示: 线程类头文件: // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at chenshuo dot com) //线程类 #ifndef MUDUO_BASE_THREAD_H #d…
muduo里的CountDownLatch类实际上是对条件变量condition进行的封装,既可以用于所有子线程等待主线程发起 "起跑" ,也可以用于主线程等待子线程初始化完毕才开始工作. condition.h代码如下: // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chen…
原子性操作可以做到比互斥锁更小的开销,在多线程编程中原子性操作是非常有用的.Atomic.h文件位于muduo/base下,代码如下: // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at chenshuo dot com) //原子性操作:比锁的开销更小 #ifndef…
muduo库线程特定数据源码文件为ThreadLocal.h //线程本地存储 // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at chenshuo dot com) #ifndef MUDUO_BASE_THREADLOCAL_H #define MUDUO_BASE…
muduo库中线程本地单例类封装代码是ThreadLocalSingleton.h 如下所示: //线程本地单例类封装 // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at chenshuo dot com) #ifndef MUDUO_BASE_THREADLOCALS…
线程安全使用单例模式,保证了每次只创建单个对象,代码如下: Singleton.h // Use of this source code is governed by a BSD-style license // that can be found in the License file. // // Author: Shuo Chen (chenshuo at chenshuo dot com) //线程安全 #ifndef MUDUO_BASE_SINGLETON_H #define MUD…
Exception类是为异常捕获而设计,可以获得异常的信息以及栈的回溯信息 (原来的代码没有demangle成员函数,输出的格式比较难看,加了demangle成员函数,利用demangle成员函数可以转换格式,使得输出的格式更加接近我们的习惯) 以下的代码是加入了demangle成员函数后的: Exception.h // Use of this source code is governed by a BSD-style license // that can be found in the…
