  • Field Details

    • memoryManagementStrategy

      @NonNull public MapContext.MemoryManagementStrategy memoryManagementStrategy

      The default setting MemoryManagementStrategy.DYNAMIC is suitable for common cases. The map data cache can adjust dynamically to fit visible data. When the visible data needs extra memory, it would increase. When it's not needed, it will reduce to a limit which is calculated internally or by using tileCacheMemoryLimitInKiB option. The MemoryManagementStrategy.FIXED would be only useful when there is very strict memory consumption requirement for the application. It potentially can have flickering visual artifacts when the map data to be visualized is very large and exceeds the cache limit.

    • tileCacheMemoryLimitInKiB

      @Nullable public Integer tileCacheMemoryLimitInKiB

      Tile cache memory limit in kibibytes. Non-positive values or null are ignored. Default value is null. Low tile cache limit will lead to eviction of tiles only if MemoryManagementStrategy is set to FIXED.

    • videoMemoryLimitInKiB

      @Nullable public Integer videoMemoryLimitInKiB

      Target video memory limit in kibibytes. Non-positive values or null are ignored. Default value is null.

    • sceneLoadCacheOptions

      @Nullable public MapContext.SceneLoadCacheOptions sceneLoadCacheOptions

      Scene load cache options. Default value is null. When loading scenes into MapScene, an internal cache is used for speeding up subsequent loads of the same scene. The cache utilizes some amount of memory for each entry and MapContext.SceneLoadCacheOptions allows customization according to the memory profile of the client: under memory constrained conditions the number of entries in this cache can be reduced or the cache can be disabled entirely, and for clients that circle through many scenes, the cache capacity can be increased.
