IInitialize 1.0.1

IInitialize is an interface that defines a contract for initialization processing. Implementing this interface indicates that an object requires an initialization phase.

This interface provides a single event, Initialize, which is raised when the initialization process is complete.

The Initialize event uses the generic InitializeEventHandler<TSender> delegate, where TSender represents the type of the object that raised the event. Event handlers receive an InitializeEventArgs object, which can contain arguments related to the initialization process, such as information about already initialized properties.

By utilizing this interface, other components or services can asynchronously be notified of the initialization completion of objects implementing IInitialize. This can be useful for scenarios such as starting dependent processes or updating the UI after initialization.

Key Elements:

• IInitialize(Of TSender): The interface to be implemented by objects requiring initialization. TSender specifies the type of the object raising the event.
• InitializeEventHandler(Of TSender) Delegate: Defines the type for the Initialize event's handlers.
• Initialize Event: An event that is raised when initialization processing is complete.
• InitializeEventArgs Class: Provides arguments related to the event, such as information about already initialized properties.

Providing this interface as a library allows you to establish a consistent initialization pattern across your applications, improving code reusability and maintainability.

(Usage Example for C# Developers):

Here's a basic example of how a C# class might implement and use the IInitialize interface, noting that InitializeEventArgs is nullable:

public class MyService : IInitialize<MyService>
{
    public event InitializeEventHandler<MyService> Initialize;

    public void BeginInitialization()
    {
        // Perform initialization tasks here
        Console.WriteLine("MyService is initializing...");
        OnInitialize(null); // InitializeEventArgs can be null
    }

    protected virtual void OnInitialize(InitializeEventArgs? e)
    {
        Initialize?.Invoke(this, e);
    }
}

public class Consumer
{
    public Consumer(MyService service)
    {
        service.Initialize += (sender, e) =>
        {
            Console.WriteLine("MyService has been initialized!");
            // Perform actions that depend on MyService being initialized
        };
    }
}
