Class
ShumateFileCache
Description [src]
class Shumate.FileCache : GObject.Object {
parent_instance: GObject
}A cache that stores and retrieves tiles from the file system. It is mainly
used by ShumateTileDownloader, but can also be used by custom data sources.
The cache will be filled up to a certain size limit. When this limit is reached, the cache can be purged, and the tiles that are accessed least are deleted.
ETags
The cache can optionally store an ETag string with each tile. This is useful to avoid redownloading old tiles that haven’t changed (for example, using the HTTP If-None-Match header).
