Search the cache list to see if a given key already exists.
Returns true if the key is found, false otherwise.

vtkTextureImageCache< Key >::CacheData & vtkTextureImageCache< Key >::GetCacheData | ( | const Key & | key | ) |
Return the cache associated to a key.
If the key doesn't exist yet in the cache list, create a new cache. The returned cache is moved at the beginning of the cache list for faster search next time. The most use cache is faster to be searched.
