TSLViewShedDataLayerCallbacks Class Reference

Detailed Description

This callback class is used by the TSLViewshedDataLayer to notify the application when viewshed operations have been performed.

If the application has set the datalayer to load asynchronously using TSLViewshedDataLayer::setSynchronousLoading( false ) it should provide an implementation of this class to TSLViewshedDataLayer::setCallbacks.

These callbacks will always be called by the layer, including when performing calculations synchronously.

These callbacks may be made from any thread including the application's foreground thread.

The callback implementation provided to the datalayer must not be deleted before the datalayer as callbacks may be made while the datalayer is being destroyed.
