IORImpl

public class IORImpl extends IdentifiableContainerBase implements IOR
An IOR is represented as a list of profiles. Only objects that extend TaggedProfile should be added to an IOR. However, enforcing this restriction requires overriding all of the addXXX methods inherited from List, so no check is included here.

Constructors Summary
public IORImpl(ORB orb)
Construct an empty IOR. This is needed for null object references.

	this( orb, "" ) ;
    
public IORImpl(ORB orb, String typeid)

	factory = orb ;
	wrapper = IORSystemException.get( orb,
	    CORBALogDomains.OA_IOR ) ;
	this.typeId = typeid ;
    
public IORImpl(ORB orb, String typeId, IORTemplate iortemp, ObjectId id)
Construct an IOR from an IORTemplate by applying the same object id to each TaggedProfileTemplate in the IORTemplate.

	this( orb, typeId ) ;

	this.iortemps = IORFactories.makeIORTemplateList() ;
	this.iortemps.add( iortemp ) ;
    
	addTaggedProfiles( iortemp, id ) ;
	
	makeImmutable() ;
    
public IORImpl(ORB orb, String typeId, IORTemplateList iortemps, ObjectId id)
Construct an IOR from an IORTemplate by applying the same object id to each TaggedProfileTemplate in the IORTemplate.
