Value members
Concrete methods
Retrieves a value from the cache or the underlying store (if not found in the cache), where a non-transactional format exists.
Retrieves a value from the cache or the underlying store (if not found in the cache), where a non-transactional format exists.
If no value is found for the current path, this will try to read the most recent entry along the path.
- Type Params
- A
the type of value stored
- Value Params
- format
the format to use for the value
- key
key at which the entry is stored
- path
access path for the read
- tx
the current transaction
- Returns
the most recent value found, or
Noneif a value cannot be found for the given path, neither in the cache nor in the persistent store.- Definition Classes

Stores an entry in the cache for which a non-transactional format exists.
Stores an entry in the cache for which a non-transactional format exists.
Note that the caller is responsible for monitoring this call, and if necessary installing
a before-commit handler which will call into the abstract method flushCache().

Inherited methods
This method should be invoked from the implementations flush hook after it has
determined the terminal version at which the entries in the cache are written
to the persistent store. If this method is not called, the cache will just
vanish and not be written out to the persistent store.

Removes an entry from the cache, and only the cache. This will not affect any
values also persisted to persistent! If the cache does not contain an entry
at the given key, this method simply returns.
