Class ValueBaseHolder
- java.lang.Object
-
- org.omg.CORBA.ValueBaseHolder
- All Implemented Interfaces:
- Streamable
public final class ValueBaseHolder extends Object implements Streamable
The Holder for ValueBase
. For more information on Holder files, see "Generated Files: Holder Files".
A Holder class for a java.io.Serializable
that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL ValueBase
as an "out" or "inout" parameter, the programmer must pass an instance of ValueBaseHolder
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 myValueBaseHolder
is an instance of ValueBaseHolder
, the value stored in its value
field can be accessed with myValueBaseHolder.value
.
