Package mdp :: Package caching :: Class cache

Class cache

Context manager for the 'cache_execute' extension.

This allows using the caching extension using a 'with' statement, as in:

>>> with mdp.caching.cache(CACHEDIR):                    # doctest: +SKIP
...     # 'node' is executed caching the results in CACHEDIR
...     node.execute(x)

If the argument to the context manager is not specified, caching is done in a temporary directory.

(Constructor)

Activate caching extension.

By default, the cache is activated globally (i.e., for all instances of Node). If cache_classes or cache instances are specified, the cache is activated only for those classes and instances.

Parameters:

cachedir - The root of the joblib cache, or a temporary directory if None
cache_classes - A list of Node subclasses for which caching is activated. Default value: None
cache_classes - A list of Node instances for which caching is activated. Default value: None

Overrides: object.__init__
