public final class ObjectHolder extends Object implements Streamable
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.
