org.omg.CORBA
public final class ObjectHolder extends Object implements Streamable
Object
that is mapped into
java org.omg.CORBA.Object
.
The holders have several application areas. The end user usually
sees them implementing CORBA methods where the primitive type
is passed by reference. While CORBA (or, for example, C) supports
this, the java does not and a wrapper class is required.
