Interfaceosid.voting.BallotPollsSession
Implementsosid.OsidSession
Description

This session provides methods to retrieve Ballot to Polls mappings. A Ballot may appear in multiple Polls. Each Polls may have its own authorizations governing who is allowed to look at it.

This lookup session defines several views:

  • comparative view: elements may be silently omitted or re-ordered
  • plenary view: provides a complete result set or is an error condition
MethoduseComparativePollsView
Description

The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
