Implementations must be thread-safe due to potential multi-threaded method calls. It defines a `NO_TILE` field, indicating the absence of a tile at a specific coordinate. The core method, `getTile`, takes x, y coordinates, and zoom level to return a `Tile`. If no tile is available, it should return `NO_TILE`; if the tile can't be fetched at that moment, it returns null. `UrlTileProvider` is an example of an implementation that is a partial one.\n"]]
