1.1 Business process

Purpose

All business logic is placed in a single layered unit called a business process. The business process represents a logical unit that handles a single business requirement that can be easily reused throught our application.

The business process contains 3 layers:

• Auth
• Validate
• Handle

How to use

public class MyBusinessProcess : BusinessProcess<int, int, int, VoidResult>
{
    /// <summary>
    /// Auth process
    /// </summary>
    /// <param name="input1"></param>
    /// <param name="input2"></param>
    /// <param name="input3"></param>
    /// <returns></returns>
    public override VoidResult Auth(int input1, int input2, int input3)
    {
        return Ok();
    }

    /// <summary>
    /// Validate process
    /// </summary>
    /// <param name="input1"></param>
    /// <param name="input2"></param>
    /// <param name="input3"></param>
    /// <returns></returns>
    public override VoidResult Validate(int input1, int input2, int input3)
    {
        return BeginValidation()
            .Validate(new MySpecification1(), input1);
            .Validate(new MySpecification2(), input2);
            .Validate(new MySpecification3(), input3)
            .ReturnResult();
    }

    /// <summary>
    /// Handle process
    /// </summary>
    /// <param name="input1"></param>
    /// <param name="input2"></param>
    /// <param name="input3"></param>
    /// <returns></returns>
    public override VoidResult Handle(int input1, int input2, int input3)
    {
        return Ok();
    }
}
