org.omg.CORBA

Class ObjectHolder

public final class ObjectHolder extends Object implements Streamable

A holder for CORBA 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.
