GetOrAdd<TKey, TResult>(ICacheEnumerable<TKey>, string, IDependency, Func<TResult>)

Gets the value for the specified key from the cache, or if the key does not exists, adds a value to the cache using the specified function delegate valueFactory.

public static TResult GetOrAdd<TKey, TResult>(this ICacheEnumerable<TKey> cache, string key, IDependency dependency, Func<TResult> valueFactory)

Parameters

cache ICacheEnumerable<TKey>

The ICacheEnumerable<TKey> to extend.

key string

The unique identifier for the cache entry.

dependency IDependency

An IDependency implementations that monitors changes in the state of the data which a cache entry depends on. If a state change is registered, the cached entry becomes invalid and is removed from the cache.

valueFactory Func<TResult>

Returns

TResult

The value for the specified key. This will either be the existing value if the key is already in the cache, or the new value returned by valueFactory if the key was not in the cache.

Type Parameters

TKey

The type of the key in the cache.

TResult

The type of the value in the cache.

GetOrAdd<TKey, TResult>(ICacheEnumerable<TKey>, string, string, IDependency, Func<TResult>)

Gets the value for the specified key from the cache, or if the key does not exists, adds a value to the cache using the specified function delegate valueFactory.
