Can you explain the concept of strategies in the Moxy library and how they are used when implementing slots?

In the Moxy library, Strategy is a way to manage how presenter method calls are passed to the View. Strategies determine how and when interface updates are displayed, especially if the View is temporarily unavailable (for example, during screen rotation).

Main strategies in Moxy:

• AddToEndStrategy — method calls are accumulated in a queue and executed in the order they were added when the View becomes available.
• OneExecutionStateStrategy — the method is executed once and is not saved for a repeat call.
• SkipStrategy — the method call is not saved and is only executed if the View is available at the time of the call.

When implementing slots, strategies help control how interface updates are accumulated and replayed, ensuring correct behavior when changing the View's state. For example, if the user rotates the screen, the strategy guarantees that all important calls will be repeated on the new View instance.

Example of using a strategy:

@StateStrategyType(AddToEndStrategy.class)
public interface MyView extends MvpView {
    void showData(String data);
}

public class MyPresenter extends MvpPresenter<MyView> {
    public void loadData() {
        // after loading data, the call to showData will be saved and executed when the View is available
        getViewState().showData("Hello, Moxy!");
    }
}
