IORInterceptorImpl

public class IORInterceptorImpl extends LocalObject implements IORInterceptor
This class implements the IORInterceptor for JTS. When an instance of this class is called by the ORB (during POA creation), it supplies appropriate IOR TaggedComponents for the OTSPolicy / InvocationPolicy associated with the POA, which will be used by the ORB while publishing IORs.
