Detailed Description

Represents the tiling scheme used by a cached map service. The tiling scheme describes how the map is broken up into tiles of images and how a client can use these tiles to display a map.

TileInfo may be declared or instantiated but it cannot be modified after creation. You may declare a TileCache object but property binding will not affect the values. You may also create a TileInfo object with the ArcGISRuntimeEnvironment.createObject method.

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

See also TileCache.
