OSID - osid.workflow.WorkflowEventLookupSession Service Interface Definition

Interface	osid.workflow.WorkflowEventLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `WorkflowEvents.` 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 office view: All workflow event methods in this session operate, retrieve and pertain to workflow events defined explicitly in the current office. federated office view: All workflow event methods in this session operate, retrieve and pertain to all workflow events defined in this office and any other wokflow events implicitly available in this office through office inheritence.
Method	getOfficeId
Description	Gets the `Office` `Id` associated with this session.
Return	`osid.id.Id`		the `Office Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getOffice
Description	Gets the `Office` associated with this session.

Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupWorkflowEvents
Description	Tests if this user can look up workflow events. A return of true does not guarantee successful authorization. A return of false indicates that it is known changing a step sequence in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer lookup operations to an unauthorized user.
Return	`boolean`		`false` if workflow event lookups is not authorized, `true` otherwise
