可移植拦截器的电流（也被称为 PICurrent）仅仅是一个槽表，其中槽由每个服务使用它们的上下文之间的数据传递他们的背景和要求的或答复的服务上下文。每个服务都需要使用picurrent储备槽或槽在初始化时使用这些槽的请求和回复的处理中。

前一个调用了，PICurrent通过电话ORB.resolve_initial_references( "PICurrent" )获得。在拦截点，对picurrent已从螺纹范围移动到请求范围的数据是可以通过在RequestInfo对象的get_slot操作。一个picurrent仍然可以通过resolve_initial_references，但那是拦截器的picurrent螺纹范围。
