每个方法都提供了一个回调对象，这样就可以在完成远程过程调用后收到异步通知。
Each method provides a callback object so that you are notified asynchronously when the remote procedure call is complete.
如果在异步调用过程中出现错误，则通知用户。
Notify the user if an error occurred during the asynchronous call.
藉由这个新的接口，开发人员可以实现service异步调用过程中的细粒度通知，但它并没有提供Callback类中的轮询机制。
This new interface allows for finer grained notifications during the asynchronous invocation of a service, but it does not provide the polling mechanism formerly found in the Callback class.
由于此过程是异步调用的，业务状态机将转换到AwaitingApproval状态，在该状态中将等待经理批准或不批准订单。
Since this process is invoked asynchronously, the business state machine transitions to the Awaiting Approval state where it will wait for the manager to approve or disapprove the order.
这个函数使用asyncrequest类发送异步请求，实现远程过程调用。
This function raises the remote procedure call invocation using the AsyncRequest class to send asynchronous requests.
下面这些值只用在长期运行的子过程，它们通过异步接口被长期运行的流程调用。
The following values apply only to long-running child processes that have been invoked by a long-running process through a synchronous interface.
这能让您不用再手工处理异步调用过程中发生的异常。
This relieves you of manually handling exceptions that occur during an asynchronous call.
例如，规则的执行触发一个业务过程，这个过程异步地调用一个服务。
An example would be the rule execution triggering a business process, which asynchronously calls a service.
在其执行过程中，BPEL流程将调用一个异步服务，方法是将另一消息放在名为IMPORTQ的MQ出站队列。
During its execution, the BPEL process will invoke an asynchronous service by placing another message on an outgoing MQ queue called IMPORTQ.
在异步调用过程中，当目标组件发生系统异常时，消息会回滚到传入目的地，并被重新提交。
When a system exception occurs at the target component during an asynchronous invocation, the message is rolled back to the incoming destination and redelivered.
与Seam的远端调用不同，JSF生命周期在Ajax4jsf异步请求过程中是活动的，因而需要servlet过滤器而非常规的 servlet。
Unlike Seam's remote calls, however, the JSF life cycle is active during an asynchronous Ajax4jsf request, hence the need for a servlet filter rather than a regular servlet.
因此，该流程结合使用了几种Lombardi技术，包括Coach、SQL、存储过程调用、Ajax更新和异步消息传递。
The process therefore USES a combination of Lombardi techniques, including Coaches, SQL, stored procedure invocation, Ajax updates and asynchronous messaging.
告诉我们，接下来的赋值过程将使用异步的方式，而ReadAsync函数为BeginRead和EndRead方法如何被调用提供了规范。
"Tells us that the bind will be made asynchronously, and the ReadAsync function provides the specification of how the BeginRead and EndRead methods should be called."
如果此过程耗时数秒，这对于异步调用而言是很常见的，而该匿名类可能在不经意间被晋升为垃圾回收器中更昂贵的1代或2代对象[3]。
If this takes several seconds, which is not uncommon for an asynchronous call, the anonymous class may be inadvertently promoted to the more expensive generation 1 or 2.
触发消息是异步和可靠的。触发消息通过调度服务的远端过程调用(rpc)消息进行传递，因此它们可能不会在消息生成后立即就被发送。
Trickle messages are asynchronous and reliable. Trickle messages are conveyed in scheduler RPC messages, so they may not be delivered immediately after being generated.
