WeakenedCache
Acts like a regular cache but with the ability to make its entries weakly referenced
Create cache
var cache = new WeakenedCache();
Fill it
var instance1 = new SampleRefType(1);
var instance2 = new SampleRefType(2);
var instance3 = new SampleRefType(3);
cache.Put(Key1, instance1, WeakenedCache.Priority.Low);
cache.Put(Key2, instance2, WeakenedCache.Priority.Normal);
cache.Put(Key3, instance3, WeakenedCache.Priority.High);
var instance2 = new SampleRefType(2);
var instance3 = new SampleRefType(3);
cache.Put(Key1, instance1, WeakenedCache.Priority.Low);
cache.Put(Key2, instance2, WeakenedCache.Priority.Normal);
cache.Put(Key3, instance3, WeakenedCache.Priority.High);
Get values
(cache.Take(Key1) as SampleRefType).Value; // 1
or use generic
cache.Take<SampleRefType>(Key2)?.Value; // 2
cache.Take<SampleRefType>(Key3)?.Value; // 3
cache.Take<SampleRefType>(Key3)?.Value; // 3
Weaken items of some priorities
cache.WeakenUpTo(WeakenedCache.Priority.Normal);
Put items with expiration of Weaken type
var someInstance = new SampleRefType();
cache.Put(
key: Key4,
value: someInstance,
priority: WeakenedCache.Priority.Normal,
expiration: TimeSpan.FromSeconds(10),
expirationType: WeakenedCache.ExpirationType.Weaken);
cache.Put(
key: Key4,
value: someInstance,
priority: WeakenedCache.Priority.Normal,
expiration: TimeSpan.FromSeconds(10),
expirationType: WeakenedCache.ExpirationType.Weaken);
Or Clear type
var otherInstance = new SampleRefType();
cache.Put(
key: Key5,
value: otherInstance,
priority: WeakenedCache.Priority.Normal,
expiration: TimeSpan.FromSeconds(10),
expirationType: WeakenedCache.ExpirationType.Clear);
cache.Put(
key: Key5,
value: otherInstance,
priority: WeakenedCache.Priority.Normal,
expiration: TimeSpan.FromSeconds(10),
expirationType: WeakenedCache.ExpirationType.Clear);
