Business Name : BooleanValue

This class provides a wrapper over a nullable boolean and provides three gate logic


Creating a boolean value three ways

BL bool1, bool2, bool3;
bool1 = false; // from a .NET boolean
bool2 = new BL(false); // using constructor
bool3 = coll1.Count > 0; // using logic

Using the BL class

// In an ASPX page, determing if current user is administrator
BL isAdmin = User.IsInRole("Administrators");
// where response is an Everest message
BL patientFound = response.controlActEvent.Subject.Count > 0;
if(isAdmin && patientFound)
    Console.Write("You may edit this patient");
else if(!patientFound)
    Console.Write("Could not find the patient");
else if(!isAdmin)
    Console.Write("You are not an administrator");
