Remote method calls still use call-by-value semantics of which you certainly need to be aware.

远程方法调用仍然使用按值调用(call - by - value)语义，您当然需要知道该语义。

youdao

Accessors for immutable properties will always have value semantics and do not need the defensive copying on either side of the call, making them more efficient.

不可变属性的存取器将总是具有值引用，因而调用的任何一方都不需要防御性复制，这使得它们效率更高。

youdao

The Object Request Broker (ORB) pass by reference option determines if pass by reference or pass by value semantics should be used when handling parameter objects involved in an EJB request.

Object Request Broker (ORB) 通过引用传递选项确定，在处理 EJB 请求中涉及的参数对象时应该使用通过引用传递还是通过值传递语义。
