Member Functions Documentation

addData(int, int *, IAlfVariantType *)

void addData ( int aNumContainerIndices,
int * aContainerIndices,
IAlfVariantType * aData
) [pure virtual]

Add a number of data fields in the model data. All model change observers are notified about the change.

Since
S60 ?S60_version

Parameters

int aNumContainerIndices The number of indices in aContainerIndices.
int * aContainerIndices The container indices to find the correct location in the data hierarchy. The ownership is transferred.
IAlfVariantType * aData The new data.

addModelChangeObserver(IAlfModelChangeObserver &)

void addModelChangeObserver ( IAlfModelChangeObserver & aObserver ) [pure virtual]

Add a new observer to be notified of any changes in the model.

Exceptions
std::bad_alloc

Since
S60 ?S60_version

Parameters

IAlfModelChangeObserver & aObserver The model change observer to be added.
