Member Functions Documentation

InstallProgress(MNcdInstallOperation &, TNcdProgress)

void	InstallProgress	(	MNcdInstallOperation &	aOperation,
			TNcdProgress	aProgress
		)	[pure virtual]

Called when install has progressed.

Note:

This will be called only once per an installed file. The reason for this is that the install process is handled outside of Catalogs Engine in the platform installer.

Parameters

MNcdInstallOperation & aOperation	The operation that sent the event.
TNcdProgress aProgress	Progress of the operation.

OperationComplete(MNcdInstallOperation &, TInt)

void	OperationComplete	(	MNcdInstallOperation &	aOperation,
			TInt	aError
		)	[pure virtual]

Called when an operation has been completed.

Parameters

MNcdInstallOperation & aOperation	The operation that sent the event.
TInt aError	Error code for operation completion. KErrNone for successful completion, KErrAbort if the user cancelled the operation, otherwise a system wide error code.

QueryReceived(MNcdInstallOperation &, MNcdQuery *)

void	QueryReceived	(	MNcdInstallOperation &	aOperation,
			MNcdQuery *	aQuery
		)	[pure virtual]

Called when a query has been received for an operation.

Note:

Querys need to be completed with MNcdOperation::CompleteQueryL() to continue the operation! Alternatively, the operation must be cancelled.

MNcdOperation MNcdQuery MNcdOperation::CompleteQueryL()

Parameters

MNcdInstallOperation & aOperation	Uncounted reference to the operation that sent the event.
MNcdQuery * aQuery	Pointer to the query that must be completed. Counted, Release() must be called after use.
