StubIORImpl

public class StubIORImpl extends Object
This class implements a very simply IOR representation which must be completely ORBImpl free so that this class can be used in the implementation of a portable StubDelegateImpl.

Fields Summary
private int
hashCode
private byte[]
typeData
private int[]
profileTags
private byte[]
profileData
Constructors Summary
public StubIORImpl()

	hashCode = 0 ;
	typeData = null ;
	profileTags = null ;
	profileData = null ;
public StubIORImpl(org.omg.CORBA.Object obj)

	// write the IOR to an OutputStream and get an InputStream 
	OutputStream ostr = StubAdapter.getORB( obj ).create_output_stream();
