Memorize

A simple .NET Standard library to memoize a function with a single parameter

Examples

• Cache the result of a function taking a non-nullable object:

int MyComplexMathOperation(int i)
{
    Thread.Sleep(10000); // Sleep 10 seconds.
    return ++i;
}

var memoize = new Memorizer<int, int>(MyComplexMathOperation);
Console.WriteLine(memoize.Invoke(2)); // Takes some time
Console.WriteLine(memoize.Invoke(2)); // Instant

• Cache the result of a function taking a nullable object:

// inb4 deleting this breaks React
string MySlowAndWeirdLeftPad(string str)
{
    Thread.Sleep(10000); // Sleep 10 seconds.
    return str == null ? "Hello" : str.PadLeft(10);
}

var memoize = new NullableMemorizer<string, string>(MySlowAndWeirdLeftPad);
Console.WriteLine(memoize.Invoke(null)); // Takes some time
Console.WriteLine(memoize.Invoke(null)); // Instant

Additional utilities are provided for your convenience:

• bool IsResultMemorized(T param): Verify if a result has been cached
• void ClearMemorizedResults(): Clear the cache
• TResult GetMemorizedResult(T param): Get a cached result
• bool TryGetMemorizedResult(T param, out TResult result): Try getting a cached result
