Detailed Description

Encapsulates the management of data provider for Data-Driven Exclusive Activity Host.

This is a helper class for Data-Driven Exclusive Activity Host classes.

Constructor & Destructor Documentation

kanzi::ActivitySourceController::ActivitySourceController ( DataDrivenExclusiveActivityHostConcept &  node )

Member Function Documentation

DataContextSharedPtr kanzi::ActivitySourceController::getActivityData

(

int

index

)

const

Gets Activity data for index.

Parameters

index

Index of item for which data is requested.

Returns

The DataContext object at the given index in the DataObject. An Empty object if the DataObject does not exist for the given index.

size_t kanzi::ActivitySourceController::getCount

(

)

const

Gets the number of objects known by the activity source controller in the given activity list source.

You can calculate the last index as ('count' - 1).

Returns

The number of objects in the activity list source.

void kanzi::ActivitySourceController::onActivitySourceDisabled

(

)

Disables the internal Activity source list.

This method must be called when the ActivitySourceProperty is removed from the Data-Driven Exclusive Activity Host. ActivitySourceController observes the changes in the ActivitySourceProperty with an internal binding. This binding does not get a notification when the ActivitySourceProperty is removed from the Data-Driven Exclusive Activity Host, hence this method is needed to notify the Data-Driven Exclusive Activity Host. Setting or reattaching the ActivitySourceProperty notifies the ActivitySourceController, eventually updating the Activity source.
