LongHolder

java.lang.Object
- org.omg.CORBA.LongHolder

All Implemented Interfaces:

Streamable
```
public final class LongHolder
extends Object
implements Streamable
```
The Holder for Long. For more information on Holder files, see "Generated Files: Holder Files".
A Holder class for a long that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL long long as an "out" or "inout" parameter, the programmer must pass an instance of LongHolder 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 myLongHolder is an instance of LongHolder, the value stored in its value field can be accessed with myLongHolder.value.

Since:

JDK1.2
