Detailed Description

CActiveBackupClient provides a connection to the Secure Backup Server for a data owning process.

It can be used to obtain information about an active backup or restore operation. It can also be used to signal to the Secure Backup Server when the data owner is ready for backup or restore.

It is also used by data owners that implement active backup or restore to provide a MActiveBackupDataClient implementation.

This class owns a RActiveBackupSessionImpl instance and publishes the public API to the outside world. The reason for this facade class is twofold:

Hiding the implementation details of RActiveBackupSessionImpl

Future binary compatibility

Member Function Documentation

BURModeInfoL ( TDriveList &, TBURPartType &, TBackupIncType & )

IMPORT_C void	BURModeInfoL	(	TDriveList &	aDriveList,
			TBURPartType &	aBackupType,
			TBackupIncType &	aIncBackupType
		)

This method returns the type(s) of backup / restore operation currently active

Parameters
aDriveList	list of drives involved in backup and restore
aBackupType	enumerated type indicating whether a backup or restore is in progress and whether full or partial.
aIncBackupType	enumerated type indicating whetherr a backup is base or incremental.

ConfirmReadyForBURL ( TInt )

IMPORT_C void

ConfirmReadyForBURL

(

TInt

aErrorCode

)

This method is called to indicate to the Secure Backup Server that the data owner is ready to participate in backup or restore. The data owner must call this method to indicate readiness or the Secure Backup Server will not request or supply backup data.

N.B. The Secure Backup Server will supply snapshot data (if relevant) before a data owner indicates readiness as it assumes that the data owner requires snapshot data in order to prepare for a backp or restore.

Parameters
aErrorCode	this should be set to KErrNone when the client is ready for backup or restore. If it is set to any other value then it indicates that the client cannot continue with the backup or restore and the error code will be supplied to the remote backup client.

DoesPartialBURAffectMeL ( )

IMPORT_C TBool

DoesPartialBURAffectMeL

(

)

This method can be called when a partial backup or restore is active and will indicate whether the calling process is expected to take part. If a full backup or restore is active then this method will return ETrue for all data owners. If no backup or restore is active then this method will return EFalse for all data owners.

Return Value: ETrue if the calling data owner is involved in the current backup or restore operation.

NewL ( )

IMPORT_C CActiveBackupClient *

NewL

(

)

[static]

This method creates a CActiveBackupClient, connects to the Secure Backup Server and does not wish to be called back so does not supply an implementation of MActiveBackupDataClient.

If this is called when the Secure Backup Server is not active then it will leave with KErrNotSupported.

Return Value: Pointer to a created CActiveBackupClient object

NewL ( MActiveBackupDataClient * )

IMPORT_C CActiveBackupClient *

NewL

(

MActiveBackupDataClient *

aClient

)

[static]

This method creates a CActiveBackupClient, connects to the Secure Backup Server and supplies a pointer to a MActiveBackupDataClient implementation.

If this is called when the Secure Backup Server is not active then it will leave with KErrNotSupported.

Parameters
aClient	pointer to an object that implements the MActiveBackupDataClient mixin. If this is NULL then the data owner does not take part in active backup or restore.

Return Value: Pointer to a created CActiveBackupClient object

Leave Codes
Release	only - If an ActiveScheduler is not installed

Panic Codes
KErrNotFound	Debug only - If an ActiveScheduler is not installed
