CachedFunc

[Deprecated, use CachedFunc2 instead]

Provide a way to create a function that can cache results of previous runs.

Getting Started

For .Net Standard >= 2.0 (including .Net Framework >= 4.6.1), get package from Nuget: MagicEastern.CachedFunc.Core

For .Net Framework 4.5s, get package from Nuget: MagicEastern.CachedFunc.Net45

How to Use

Assume there is a slow-running function.

static int SlowFunc(int n) {
    Thread.Sleep(1000);
    return n;
}

Starting from version 2.0.0, I added some extension method on Func<> delegate for ease of use. You can create a cached function from Func<> directly.

CachedFunc<int, int> cachedFunc = ((Func<int, int>)SlowFunc).ToCachedFunc(
    new CachedFuncOptions { 
        AbsoluteExpirationRelativeToNow = new TimeSpan(1, 0, 0) 
    }
)

Then, you have a cached function. Call this function in the same way as the orignal function.

int result = cachedFunc(12345);
