OSID - osid.workflow.event.WorkflowEventOfficeAssignmentSession Service Interface Definition

Interface	osid.workflow.event.WorkflowEventOfficeAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.workflow.event.WorkflowEventManager`
Used By	`osid.workflow.event.WorkflowEventProxyManager`
Description	This session provides methods to re-assign `WorkflowEvents` to `Office` mappings. A `WorkflowEvent` may appear in multiple `Office` catalogs and removing the last reference to a `WorkflowEvent` is the equivalent of deleting it. Each `Office` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `WorkflowEvent` to another `Office is not a` copy operation (eg: does not change its `Id` ).
Method	canAssignWorkflowEvents
Description	Tests if this user can alter workflow event/office mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED. T` his is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
