Method Detail

### next

    public VOResource next()
                    throws RegistryServiceException,
                           RegistryFormatException,
                           RegistryCommException

  return the next resource description in the list of results. This call may recontact the registry to get the next set of results; thus, some exceptions may be thrown.

  Throws:
    `RegistryServiceException` - if the service encounters an error (i.e. on the server side).
    `RegistryCommException` - if an unexpected protocol error is encountered.
    `RegistryFormatException` - if the XML response is non-compliant in some way.

### previous

    public VOResource previous()
                        throws RegistryServiceException,
                               RegistryFormatException,
                               RegistryCommException

  return the previous resource description. This call may recontact the registry to re-fetch the previous set of results; thus, some exceptions may be thrown.

  Throws:
    `RegistryServiceException` - if the service encounters an error (i.e. on the server side).
    `RegistryCommException` - if an unexpected protocol error is encountered.
    `RegistryFormatException` - if the XML response is non-compliant in some way.
