The Holder for Object. For more information on Holder files, see 
"Generated Files: Holder Files".
 A Holder class for a CORBA object reference (a value of type org.omg.CORBA.Object). It is usually used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has a CORBA Object reference as an "out" or "inout" parameter, the programmer must pass an instance of ObjectHolder 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 myObjectHolder is an instance of ObjectHolder, the value stored in its value field can be accessed with myObjectHolder.value. 
Since:      JDK1.2
