OSID - osid.process.ProcessNotificationSession Service Interface Definition

Interface	osid.process.ProcessNotificationSession
Implements	`osid.OsidSession`
Description	This session defines methods to receive notifications on adds/changes to `Process` objects. This session is intended for consumers needing to synchronize their state with this service without the use of polling. Notifications are cancelled when this session is closed.
Method	canRegisterForProcessNotifications
Description	Tests if this user can register for `Process` notifications. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer notification operations.
Return	`boolean`		`false` if notification methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	reliableProcessNotifications
Description	Reliable notifications are desired. In reliable mode, notifications are to be acknowledged using `acknowledgeProcessNotification()` .
Compliance	`mandatory`		This method is must be implemented.
Method	unreliableProcessNotifications
Description	Unreliable notifications are desired. In unreliable mode, notifications do not need to be acknowledged.
Compliance	`mandatory`		This method is must be implemented.
Method	acknowledgeProcessNotification
Description	Acknowledge a process notification.
Parameters	`osid.id.Id`	`notificationId`	the `Id` of the notification
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForNewProcesses
Description	Register for notifications of new processes. `ProcessReceiver.newProcesses()` is invoked when a new `Process` is created.
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForChangedProcesses
Description	Registers for notification of updated processes. `ProcessReceiver.changedProcesses()` is invoked when a process is changed.
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForChangedProcess
Description	Registers for notification of an updated process. `ProcessReceiver.changedProcesses()` is invoked when the specified process is changed.
Parameters	`osid.id.Id`	`processId`	the `Id` of the Process to monitor
Errors	NULL_ARGUMENT		`processId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForDeletedProcesses
Description	Registers for notification of deleted processes. `ProcessReceiver.deletedProcesses()` is invoked when a process is deleted.
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForDeletedProcess
Description	Registers for notification of a deleted process. `ProcessReceiver.deletedProcesses()` is invoked when the specified process is deleted.
Parameters	`osid.id.Id`	`processId`	the `Id` of the `Process` to monitor
Errors	NULL_ARGUMENT		`processId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForChangedProcessHierarchy
Description	Registers for notification of an updated process hierarchy structure. `ProcessReceiver.changedChildOfProcesses()` is invoked when a node experiences a change in its children.
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForChangedProcessHierarchyForAncestors
Description	Registers for notification of an updated process hierarchy structure. `ProcessReceiver.changedChildOfProcesss()` is invoked when the specified node or any of its ancestors experiences a change in its children.
Parameters	`osid.id.Id`	`processId`	the `Id` of the `Process` node to monitor
Errors	NULL_ARGUMENT		`processId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	registerForChangedProcessHierarchyForDescendants
Description	Registers for notification of an updated process hierarchy structure. `ProcessReceiver.changedChildOfProcesses()` is invoked when the specified node or any of its descendants experiences a change in its children.
Parameters	`osid.id.Id`	`processId`	the `Id` of the `Process` node to monitor
Errors	NULL_ARGUMENT		`processId` is `null`
