Class TypeCodeHolder

|
+--org.omg.CORBA.TypeCodeHolder
- public final class TypeCodeHolder
- extends Object
- implements Streamable
A Holder class for a TypeCode
object
that is used to store "out" and "inout" parameters in IDL operations.
If an IDL operation signature has an IDL TypeCode
as an "out"
or "inout" parameter, the programmer must pass an instance of
TypeCodeHolder
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 myTypeCodeHolder
is an instance of TypeCodeHolder
,
the value stored in its value
field can be accessed with
myTypeCodeHolder.value
.
