All Implemented Interfaces:

Streamable

public final class ServiceInformationHolder

extends Object

implements Streamable

A Holder class for a ServiceInformation object that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL xxx as an "out" or "inout" parameter, the programmer must pass an instance of ServiceInformationHolder as the corresponding parameter in the method invocation; for "inout" parameters, the programmer must also fill the "in" value to be sent to the server. Before the method invocation returns, the ORB will fill in the value corresponding to the "out" value returned from the server.

If myServiceInformationHolder is an instance of ServiceInformationHolder, the value stored in its value field can be accessed with myServiceInformationHolder.value.
