构造器详细资料

CustomOfflineTdtTileLayer

public CustomOfflineTdtTileLayer(long cPtr,
                                 boolean cMemoryOwn)

CustomOfflineTdtTileLayer

public CustomOfflineTdtTileLayer(TileDataSource dataSource)

从数据源构建RasterTileLayer对象。

参数:

dataSource - 该图层加载数据的数据源。

方法详细资料

getCPtr

public static long getCPtr(CustomOfflineTdtTileLayer obj)

finalize

protected void finalize()

覆盖:

finalize 在类中 TileLayer

delete

public void delete()

覆盖:

delete 在类中 TileLayer

swigCreatePolymorphicInstance

public static CustomOfflineTdtTileLayer swigCreatePolymorphicInstance(long cPtr,
                                                                      boolean cMemoryOwn)

Creates a polymorphic instance of the given native object. This is used internally by the SDK.

参数:

cPtr - The native pointer of the instance.

cMemoryOwn - The ownership flag.

返回:

The created instance.

getTextureCacheCapacity

public long getTextureCacheCapacity()

返回瓷砖纹理缓存容量。

返回:

瓷砖纹理缓存容量。

setTextureCacheCapacity

public void setTextureCacheCapacity(long capacityInBytes)

Sets the tile texture cache capacity. Texture cache is the primary storage for raster data,
all tiles contained within the texture cache are stored as uncompressed openGL textures and can immediately be
drawn to the screen. Setting the cache size too small may cause artifacts, such as disappearing tiles.
The more tiles are visible on the screen, the larger this cache should be. A single opaque 256x256 tile takes
up 192KB of memory, a transparent tile of the same size takes 256KB. The number of tiles on the screen depends
on the screen size and density, current rotation and tilt angle, tile draw size parameter and
whether or not preloading is enabled.
The default is 10MB, which should be enough for most use cases with preloading enabled. If preloading is
disabled, the cache size should be reduced by the user to conserve memory.

参数:

capacityInBytes - The new tile bitmap cache capacity in bytes.

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

覆盖:

swigGetClassName 在类中 TileLayer

返回:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

覆盖:

swigGetDirectorObject 在类中 TileLayer

返回:

The connected director object or null if director is not connected.
