  • 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.
