All Implemented Interfaces:

Archive, java.rmi.Remote, SourceArchive

public class HTTPArchive

extends HTTPwraper

implements SourceArchive

Implement the archive via http. Although SourceArchive is remote there is no need to run HTTPArchive as a remote object it should be created locally on the client.

Fields inherited from class stsci.archive.HTTPwraper

factory, factoryName, local, name, url

Constructor Summary

HTTPArchive(ArchiveDescriptor d)
Handled by the super class.

Method Summary

RemoteIter	area(double alpha, double delta, double radius) The most simple interface is an area search specified by alpha,delta and width of a box.
RemoteIter	area(double alpha, double delta, double radius, java.lang.String predicate) Must also support this plus some predicate to cut down on the number entries returned
RemoteIter	area(double alpha, double delta, double radius, java.lang.String[] htmsegments) Specify HTM segments but not the predicate
RemoteIter	area(double alpha, double delta, double radius, java.lang.String predicate, java.lang.String[] htmsegments) We can make an area even more efficient by allowing the specification of which HTM seqments we want.
ArchiveObject	lookup(java.lang.String id) We should support ID lookup for a given archive ..
RemoteIter	scan(java.lang.String classname, java.lang.String predicate) The definiton of a predicate is a little tricky.

lookup

public ArchiveObject lookup(java.lang.String id)
                     throws ArchiveException,
                            java.rmi.RemoteException

Description copied from interface: SourceArchive

We should support ID lookup for a given archive ..

lookup in interface SourceArchive

area

public RemoteIter area(double alpha,
                       double delta,
                       double radius)
                throws ArchiveException,
                       java.rmi.RemoteException

Description copied from interface: SourceArchive

The most simple interface is an area search specified by alpha,delta and width of a box.

scan

public RemoteIter scan(java.lang.String classname,
                       java.lang.String predicate)
                throws ArchiveException,
                       java.rmi.RemoteException

Description copied from interface: SourceArchive

The definiton of a predicate is a little tricky. For most systems simple boolean comparisons are okay but it gets more complex with String regular expression testing .e.g. this is not the same in Oracle and Objectivity.

Specified by:

scan in interface SourceArchive

area

public RemoteIter area(double alpha,
                       double delta,
                       double radius,
                       java.lang.String predicate)
                throws ArchiveException,
                       java.rmi.RemoteException

                throws ArchiveException,
                       java.rmi.RemoteException

Description copied from interface: SourceArchive

We can make an area even more efficient by allowing the specification of which HTM seqments we want. The server implementation would need to deal with a deapth mismatch in case there was one.
