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
MapContext.MemoryManagementOptions.tileCacheMemoryLimitInKiBoption. 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.Declaration
Swift
public var memoryManagementStrategy: MapContext.MemoryManagementStrategy -
Tile cache memory limit in kibibytes. Non-positive values or
nilare ignored. Default value isnil. Low tile cache limit will lead to eviction of tiles only if MemoryManagementStrategy is set to FIXED.Declaration
Swift
public var tileCacheMemoryLimitInKiB: Int32? -
Target video memory limit in kibibytes. Non-positive values or
nilare ignored. Default value isnil.Declaration
Swift
public var videoMemoryLimitInKiB: Int32? -
Creates a new instance.
Declaration
Swift
public init(memoryManagementStrategy: MapContext.MemoryManagementStrategy = MapContext.MemoryManagementStrategy.dynamic, tileCacheMemoryLimitInKiB: Int32? = nil, videoMemoryLimitInKiB: Int32? = nil)
