public abstract class HTTPwraper

Wrap a URL with a particular factory which can query it and produce an object or objects. This should work for any http feed if we always use a WebFactory (see factory package).

Constructor Detail

HTTPwraper

public HTTPwraper(ArchiveDescriptor d)
           throws java.rmi.RemoteException

Basically we need a factory which correspnds to the catalogue to parse the peculiarites of the web feed. This is done here by creating a class from a string which has the name of the catalogue prepended to the word factory and is in stsci.factory package - hence for the HIP archive there must exist at run time a class stsci.factory.HIPfactory. Case is important of course. The nice thing about this is ading new WEB archives only requires writting the corresponding factory and requires no change to this code.
