A cache of quantized-mesh terrain tiles.
A cache instance is associated with exactly one QuantizedMeshTerrainProvider.

SyntaxThe QuantizedMeshTerrainCache type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | QuantizedMeshTerrainCache |
Initializes a new instance.
|
Properties| Name | Description | |
|---|---|---|
 | Group |
Gets the TerrainCacheGroup that contains this cache.
(Inherited from TerrainCache.) |
| LeastRecentlyUsedRegion |
Gets the region in this cache that was least recently used.
(Overrides TerrainCacheLeastRecentlyUsedRegion.) |
| Size |
Gets the approximate total memory, in bytes, used by all regions in the cache.
(Overrides TerrainCacheSize.) |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetMesh |
Gets the terrain tile with specified tile coordinates.
If a tile satisfying the request is in the cache, it will be returned.
Otherwise, the tile will be loaded to satisfy the request,
and then a request to add that tile to the cache will be queued to the
TerrainCacheGroup thread.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| LoadRegion |
Loads the specified region into the cache.
(Overrides TerrainCacheLoadRegion(TerrainRegion).) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| PreloadExtent |
Loads the terrain data in a given extent into the terrain cache. This method does not return
until the terrain data is fully loaded. All terrain data within the extent is loaded into
memory even if doing so would exceed the TerrainCacheGroup'sMaximumSize. Furthermore, the loaded terrain data is locked
in memory (meaning it will not be unloaded) until the user calls UnloadExtent(CartographicExtent).
This method is safe to call from any thread.
|
| RemoveRegion |
Removes the specified region from the cache.
(Overrides TerrainCacheRemoveRegion(TerrainRegion).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UnloadExtent |
Unloads the cached terrain data for a given extent. This method unloads all cached
regions where any part of the region falls within the extent. It does not return
until the regions have been unloaded. However, if a region within the extent is
being used in another thread while this method is executing, the region may be
reloaded immediately after this method unloads it. This method is safe to call
from any thread.
