示例1: Action

/// Takes the control state of the provided context and from it produces
/// a view state model that is used as the basis of the view-step render
/// pipeline.
/// </summary>
/// <remarks>
/// This is what you'd override if you wanted to govern your own model presented
/// to your view layer.
/// </remarks>
/// <param name="ev">The event that gave rise to this action.</param>
public override void Action(IEvent ev)
