TServer
属性serverTransport 为TServerTransport类型,类图如下：
构造函数，简单根据args设置几个成员，大部分是工厂类：
protected TServer(AbstractServerArgs args) {
processorFactory_ = args.processorFactory; // 处理器工厂
serverTransport_ = args.serverTransport; // 服务器transport，具有listen和accept功能
inputTransportFactory_ = args.inputTransportFactory; // 输入transport
outputTransportFactory_ = args.outputTransportFactory; // 输出transport
inputProtocolFactory_ = args.inputProtocolFactory; // 输入protocol
outputProtocolFactory_ = args.outputProtocolFactory; // 输出protocol
}
public abstract void serve(); 为抽象类，供子类实现。子类有：
