Class ValueBaseHolder
java.lang.Object
|
+--org.omg.CORBA.ValueBaseHolder
- All Implemented Interfaces:
- Streamable
- public final class ValueBaseHolder
- extends Object
- implements Streamable
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.
