Interface BallotConstrainerPollsSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface BallotConstrainerPollsSession
extends OsidSession

This session provides methods to retrieve BallotConstrainer to Polls mappings. A BallotConstrainer may appear in multiple Polls objects. 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

Returns:

false if looking up mappings is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

usePlenaryBallotConstrainerPollsView

void usePlenaryBallotConstrainerPollsView()

A complete view of the BallotConstrainer and Polls returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.

Compliance:

mandatory - This method is must be implemented.
