handler

handler主要用于异步消息的处理:当发出一个消息之后,首先进入一个消息队列,发送消息的函数即刻返回,而另外一个部分在消息队列中逐一将消息取出,然后对消息进行处理,也就是发送消息和接收消息不是同步的处理。这种机制通常用来处理相对耗时比较长的操作。
  • 行为模式和同步事件调度操作

    The Reactor design pattern handles service requests that are delivered concurrently to an application by one or more clients. Each service in an application may consist of serveral methods and is represented by a separate event handler that is responsible for dispatching service-specific requests.

  • LPC1300系列产品勘误数据手册

    On the LPC13xx, programming, erasure and re-programming of the on-chip flash can be performed using In-System Programming (ISP) via the UART serial port, and also, can be performed using In-Application Programming (IAP) calls directed by the end-user code. For In-System Programming (ISP) via the UART serial port, the ISP command handler (resides in the bootloader) allows erasure of one or more sector (s) of the on-chip flash memory.

  • // This Communications Component is implemented using separate Read and Write // threads. Messages

    // This Communications Component is implemented using separate Read and Write // threads. Messages from the threads are posted to the Comm control which is // an invisible window. To handle data from the comm port, simply // attach a handler to OnReceiveData . There is no need to free the memory // buffer passed to this handler. If TAPI is used to open the comm port, some // changes to this component are needed ( StartComm currently opens the comm // port). The OnRequestHangup event is included to assist this. // // David Wann // Stamina Software // 28/02/96 // davidwann@hunterlink.net.au

  • SharpPcap c#抓包实现时时获取网卡信息

    SharpPcap c#抓包实现时时获取网卡信息 SharpPcap tutorial: a step by step guide to using SharpPcap The text of this tutorial is taken directly from WinPcap's official tutorial but is modified to show the C# use of the SharpPcap library. All examples can be downloaded together with SharpPcap source code from SharpPcap 's homepage. The WinPcap library must be installed before attempting to run any of these examples, so please download and install the latest version from WinPcap's download page. SharpPcap was written and tested using .NET v1.1 and Windows 2000/XP. I have no idea about other .NET and Windows versions. If you do try it, please report your results. The following topics are covered in this tutorial: Obtaining the device list Obtaining advanced information about installed devices Opening an adapter and capturing packets Capturing packets without the event handler Filtering the traffic Interpreting the packets Handling offline dump files Sending Packets Gathering Statistics on the network traffic 1. Obtaining the device list

  • SpringMVC设计

       springMVC有三个映射器,如果不定义映射Mapping,那么就会使默认: l   <bean class="org.springframework.web.servlet.handler.BeanNameUrlhandlerMapping"></bean> 也就是说:上面这个定义和不定义都是一样的。 不定义: <bean id="testController" name="/hello.do" class="cn.itcast.controller.TestController"></bean> 直接使用:hello.do来访问。 <!-- 简单的url映射处理器 --> l   <bean class="org.springframework.web.servlet.handler.SimpleUrlhandlerMapping">                    <property name="mappings">                             <props>          那么上面的这个映射配置:表示多个*.do文件可以访问多个Controller或者一个Controller。          前提是:都必须依赖:          <bean id="testController" name="/hello.do" class="cn.itcast.controller.TestController"></bean>          <!-- /WEB-INF/jsp/index.jsp -->          <bean class="org.springframework.web.servl                                      <prop key="/hello1.do">testController</prop>                                      <prop key="/a.do">testController</prop>                             </props>                    </property> </bean> et.view.InternalResourceViewResolver">                    <property name="prefix" value="/WEB-INF/jsp/"></property>                    <property name="suffix" value=".jsp"></property>          </bean>
