How to set up method callbacks ​

For methods of an interface it is possible to provide a callback delegate. TWIZZAR generates a Callback method for every method of an interface. The Callback method accepts a function as a parameter. The function returns void and has the method parameters as its parameters.

c#
public interface IStorage
{
    bool CheckAvailable(string ingredientName);
}

var storage = new ItemBuilder<IStorage>()
    .With(p => p.CheckAvailable.Callback(name => Console.WriteLine(name)))
    // it is also possible to provide a return value and a callback
    .With(p => p.CheckAvailable.Value(true))
    .Build();
public interface IStorage
{
    bool CheckAvailable(string ingredientName);
}

var storage = new ItemBuilder<IStorage>()
    .With(p => p.CheckAvailable.Callback(name => Console.WriteLine(name)))
    // it is also possible to provide a return value and a callback
    .With(p => p.CheckAvailable.Value(true))
    .Build();

Important

Only one callback can be set up for a method. If multiple callbacks are set up the last one will be used.
