OSID - osid.financials.budgeting.BudgetEntryLookupSession Service Interface Definition

Interface	osid.financials.budgeting.BudgetEntryLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `BudgetEntry` objects. This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition isolated business view: All budget entry methods in this session operate, retrieve and pertain to budget entries defined explicitly in the current business. Using an isolated view is useful for managing `BudgetEntries` with the `BudgetEntryAdminSession.` federated business view: All budget entry methods in this session operate, retrieve and pertain to all budget entries defined in this business and any other budget entries implicitly available in this business through business inheritence. effective budget entry view: All budget entry lookup methods return budget entries where the current date falls in between the effective dates inclusive. any effective budget entry view: Budget entries of any effective date are returned from methods. Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods `useFederatedBusinessView()` and `useIsolatedBusinessView()` behave as a radio group and one should be selected before invoking any lookup methods.
