Associate Cache

Installation

Install the nuget package AssociativeCache.4.0.0.nupkg.

Using In Memory Cache Manager

Initialise a single instance of the cache manager using with default parameters.

var cacheManager = new InMemoryCache<string, string>();

Adding a new item to cache

cacheManager.Add("key", "value");

Getting item from cache

var cacheValue = cacheManager.TryGetValue("key");

Overriding the default eviction policy (FIFO)

Current implementations include:

• First In First Out - FifoEvictionPolicy (default)
• Most Recently Used - MruEvictionPolicy
• Least Recently Used - LruEvictionPolicy

var evictionPolicy = new MruEvictionPolicy<TKey,TValue>();
var cacheManager = new InMemoryCache<string, string>(evictionPolicy);

Implementing custom eviction policy

Create a new class that derives from the interface ICacheEvictionPolicy<TKey,TValue>.

public class CustomEvictionPolicy<TKey,TValue> : ICacheEvictionPolicy<TKey,TValue>
{
        public TKey EvictItem()
        {
            //return key of item to evict
        }

        public void OnItemAdded(TKey key, TValue value)
        {
            //custom logic
        }

        public void OnItemAccessed(TKey key, TValue value)
        {
            //custom logic
        }

        public void OnItemRemoved(TKey key)
        {
            //custom logic
        }
}
