Caches.__getitem__() – diskcache-oxide

Caches.getitem()

The named plain cache: opened on first use, then the same object every time.

Usage

Caches.__getitem__(name)

A NullCache while it can’t be opened (see the class docs), or NullCache(invalidate=real) while it’s disabled. The type is TransactionalCacheLike, so caches[name].transact() checks; a cache registered with shards= is read with fanout(), whose transact takes a key.

Raises

KeyError: No cache by that name is registered.
TypeError: The cache was registered with shards= (use fanout(name)), or its settings are invalid.
ValueError: Its settings are invalid.
