CContactOpenOperation Class Reference

class CContactOpenOperation : private CActive

A class that manages the asynchronous open operation for a CContactDatabase.

The object can be deleted before the asynchronous open completes. This will set the state of the client supplied TRequestStatus to KErrCancel.

When the client supplied TRequestStatus is completed with KErrNone the TakeDatabase() method is called to pass ownership of the open database to the client.

Constructor & Destructor Documentation

CContactOpenOperation(TRequestStatus &)

CContactOpenOperation(TRequestStatus &aClientStatus)[private]

Parameters

TRequestStatus & aClientStatus

Deletes the active object.

If the asynchronous open is still in progress it is cancelled.

If the TakeDatabase() API has not been called and the database has been opened it is closed.
