MemoryCache¶

class privex.helpers.cache.MemoryCache.MemoryCache(*args, enter_reconnect: Optional[bool] = None, exit_close: Optional[bool] = None, **kwargs)[source]¶

A very basic cache adapter which implements CacheAdapter - stores the cache in memory using the static attribute __CACHE

As the cache is simply stored in memory, any python object can be cached without needing any form of serialization.

Fully supports cache expiration.

Basic Usage:

>>> from time import sleep
>>> c = MemoryCache()
>>> c.set('test:example', 'hello world', timeout=60)
>>> c.get('test:example')
'hello world'
>>> sleep(60)
>>> c.get('test:example', 'NOT FOUND')
'NOT FOUND'

__init__(*args, enter_reconnect: Optional[bool] = None, exit_close: Optional[bool] = None, **kwargs): Initialize self. See help(type(self)) for accurate signature.

`get_or_set`(key, value[, timeout])	Attempt to return the value of `key` in the cache.
`remove`(*key)	Remove one or more keys from the cache.
`set`(key, value[, timeout])	Set the cache key `key` to the value `value`, and automatically expire the key after `timeout` seconds from now.
`update_timeout`(key[, timeout])	Update the timeout for a given `key` to `datetime.utcnow() + timedelta(seconds=timeout)`
