MDiskNotifyHandlerCallback Class Reference

class MDiskNotifyHandlerCallback

Class provides a callback interface for handling the notififications from the file server. The Client derives a class from this interface and implements the HandleNotify-methods that interest it. An empty default implementation is provided for all of the methods. In debug build the default implementations print out a debug trace.

HandleNotifyDisk(TInt, const TDiskEvent &)

IMPORT_C void	HandleNotifyDisk	(	TInt	aError,
			const TDiskEvent &	aEvent
		)	[virtual]

This callback method is used to notify the client about disk notifications, i.e. memory card has been inserted

TDiskEvent

Parameters

TInt aError	System wide error code from file server
const TDiskEvent & aEvent	The disk event data data specified by TDiskEvent

HandleNotifyDiskSpace(TInt, const TDiskSpaceEvent &)

IMPORT_C void	HandleNotifyDiskSpace	(	TInt	aError,
			const TDiskSpaceEvent &	aEvent
		)	[virtual]

This callback method is used to notify the client about disk space notifications.

TDiskSpaceEvent

Parameters

TInt aError	System wide error code from file server
const TDiskSpaceEvent & aEvent	The disk space event data specified by TDiskSpaceEvent

HandleNotifyDismount(TInt, const TDismountEvent &)

IMPORT_C void	HandleNotifyDismount	(	TInt	aError,
			const TDismountEvent &	aEvent
		)	[virtual]

This callback method is used to notify the client about dismount notifications. Client have to call CDiskNotifyHandler's AllowDismount after it has finished preparing for dismount.

TDismountEvent

Parameters

TInt aError	System wide error code from file server
const TDismountEvent & aEvent	The dismount event data specified by TDismountEvent

HandleNotifyDismountFinished(TInt, const TDismountFinishedEvent &)

IMPORT_C void	HandleNotifyDismountFinished	(	TInt	aError,
			const TDismountFinishedEvent &	aEvent
		)	[virtual]

This callback method is used to notify the client when started dismount has finished.

TDismountFinishedEvent

Parameters

TInt aError	System wide error code
const TDismountFinishedEvent & aEvent	The event data specified by TDismountFinishedEvent

HandleNotifyEntry(TInt, const TEntryEvent &)

IMPORT_C void	HandleNotifyEntry	(	TInt	aError,
			const TEntryEvent &	aEvent
		)	[virtual]

This callback method is used to notify the client about entry notifications.

TEntryEvent

Parameters

TInt aError	System wide error code from file server
const TEntryEvent & aEvent	The entry event data specified by TEntryEvent

Member Enumerations Documentation

Enum TDiskEventType

Defines the disk notification types.

Enumerators

EDiskError = 0	To indicate disk notification error. It also indicates that there is no valid disk event data available.
EDiskAdded	To indicate that a new drive has been added to the drive list of file server.
EDiskRemoved	To indicate that a drive has been removed from the drive list of file server.
EDiskStatusChanged	To indicate that drive status has been changed. E.g. A memory card has been inserted, removed or unlocked.
