This accomplishes the goal of making the UI code reasonably simple; but what about the static method and passing objects by value Well, the NewCustomer() method contacts the application server and asks it to create a new Customer object with default values. The object is created on the server and then returned back to the NewCustomer() code, which is running on the client. Now that the object has been passed back to the client by value, the method simply returns it to the UI for use. Likewise, we can create a static method in the class in order to load an object with data from the data store as shown: public static Customer GetCustomer(string criteria) { AppServer svr = (AppServer) Activator.GetObject(typeof(AppServer), "http://myserver/myroot/appserver.rem"); return svr.GetCustomer(criteria); } Again, the code contacts the application server, providing it with the criteria necessary to load the object s data and create a fully populated object. That object is then returned by value to the GetCustomer() method running on the client, and then back to the UI code. As before, the UI code remains simple: Customer cust = Customer.GetCustomer(myCriteria); The class-in-charge model requires that you write static factory methods in each class, but keeps the UI code simple and straightforward. It also takes full advantage of .NET s ability to pass objects across the network by value, thereby minimizing the plumbing code in each object. Overall, it provides the best solution, which will be used (and explained further) in the chapters ahead.

The ProjectInfo object is responsible for providing read-only information about a project, while the ResourceInfo object provides read-only information about a resource. By loading the minimum amount of data required to meet these responsibilities, these objects provide a high-performance solution and follow good behavioral object design.

The ProjectData class offers a clear, abstract, and formal interface to the caller that is separate from the interface of Project itself. The ProjectData class is a data transfer object (DTO). This means that it is composed purely of public read-write properties, with no internal code. In other words, this class should exactly match the code created by Visual Studio when it creates a proxy class for a web service. In fact, if you are using XSD schemas to define the XML transferred to and from the caller, you can generate this class using the xsd.exe command line utility. In PTWebService, I wrote the class by hand, and it looks like this: public class ProjectData { private Guid _id; private string _name; private string _started; private string _ended; private string _description; private List<ProjectResourceData> _resources = new List<ProjectResourceData>(); public Guid Id { get { return _id; } set { _id = value; } } // other properties go here } You can get the complete code from the download for this book. Not only does this class include properties corresponding to those of Project, but it also includes a List<ProjectResourceData> field. I ll discuss this later, as this class will also be used by GetProjectList() and GetProject(). As you can see, component-based methods like AddProject() are relatively easy to implement. They simply accept a set of strongly typed parameters, potentially call Security.Login() and then let the business objects do all the hard work. The code in AddProject() relies on the fact that the

process.Start(); process.BeginErrorReadLine(); process.BeginOutputReadLine(); process.WaitForExit(); var elapasedTime = process.ExitTime - process.StartTime; RoleManager.WriteToLog("Information", String.Format("Command: {0} {1}", cmdPath, arguments)); RoleManager.WriteToLog("Information", String.Format("Exit Code: {0}", process.ExitCode)); RoleManager.WriteToLog("Information", String.Format("Elapsed Time: {0}", elapasedTime)); return process.ExitCode; }

The object model has a RoleList object, responsible for providing a read-only list of role data. It also has a Roles object, responsible for editing the list of roles in the application. While these two objects have very distinct responsibilities, they do have a point of interaction that should be addressed. Though not required by any use case from a user, the RoleList object can, and probably should, be cached. The list of roles won t change terribly often, yet the RoleList object will be used frequently to populate UI controls and to validate data from the user. There s no sense hitting the database every time to get the same data over and over. You ll see how to easily implement the caching in s 17 and 18, but first, there s a design issue to consider: what happens when the user edits the list of roles using the Roles object In such a case, the RoleList object will be inaccurate.

Project object will throw exceptions for any authorization violations, and that its Save() method will throw an exception if the object s validation rules are violated by the data provided from the consumer. Now let s move on to look at service-oriented, message-based web method implementations.
