public voidregister(java.lang.Class cls)
Register the ServiceContext class so that it will be recognized by the read method. Class cls must have the following properties:
  • It must derive from com.sun.corba.se.spi.servicecontext.ServiceContext.
  • It must have a public static final int SERVICE_CONTEXT_ID member.
  • It must implement a constructor that takes a org.omg.CORBA_2_3.portable.InputStream argument.

	if (ORB.ORBInitDebug)
	    dprint( "Registering service context class " + cls ) ;
	
	ServiceContextData scd = new ServiceContextData( cls ) ;

	if (findServiceContextData(scd.getId()) == null)
	    scCollection.addElement( scd ) ;
