ndi.cache

The ndi.cache module provides a simple in-memory cache for storing data.

The Cache class

The Cache class is used to create a new cache object.

__init__(self, maxMemory=10e9, replacement_rule='fifo')

Creates a new cache object.

• maxMemory: The maximum amount of memory (in bytes) that the cache can use.
• replacement_rule: The replacement rule to use when the cache is full. Can be 'fifo', 'lifo', or 'error'.

add(self, key, type, data, priority=0)

Adds an item to the cache.

• key: The key for the item.
• type: The type of the item.
• data: The data to be cached.
• priority: The priority of the item (higher priority items are less likely to be evicted).

lookup(self, key, type)

Looks up an item in the cache.

• key: The key for the item.
• type: The type of the item.

Returns the cached item, or None if the item is not found.
