Call-by-reference的意思|示意

This is Wayne's [Kelly] call, but I expect that the reference parameters will end up being passed by copying.

这是Wayne Kelly的调用，但是我期望引用参数能通过复制传递而终止。

By enabling pass by reference, the parameters of the method are not copied to the stack with every remote call, which can be expensive.

通过引用传递，方法的参数没有被复制到每个远程调用的堆栈中，而这个复制过程可能是代价高的。

The copy constructor is called because you call by value not by reference.

复制构造函数是因为你呼叫的价值不是由参考。

The first thing a session bean must do is to obtain a reference to a PersistenceManagerFactory by making a JNDI lookup call.

会话bean必须做的第一件事是通过调用JNDI查询，获得对PersistenceManagerFactory的引用。

To summarize, the ORB pass by reference option basically treats the invoked EJB method as a local call (even for EJBs with remote interfaces) and avoids the requisite object copy.

总的来说，OR B通过引用传递选项基本上将调用的EJB方法作为本地调用对待(甚至对于带远程接口的EJB)，并避免必需的对象复制操作。

The service call is made simple by helper code that is generated for each reference (you create the references in an assembly diagram, as we will explain shortly).

每个引用都会生成相应的helper代码，它将使得服务调用变得简单(在组装关系图中创建引用，我们将对其进行简单说明)。
