Roles, Responsibilities and Collaborations, Wirfs-Brock describes how complex responsibilities should be allocated:3 An object has three options for fulfilling any responsibility It can either: * Do all the work itself * Ask others for help doing portions of the work (collaborate with others) * Delegate the entire request to a helper object When you re faced with a complex job, ask whether an object is up to this responsibility or whether it is taking on too much A responsibility that is too complex to be implemented by a single object essentially introduces a new sub design problem You need to design a set of objects that will collaborate to implement this complex responsibility These objects will have roles and responsibilities that contribute to the implementation of the larger responsibility.

.NET provides a rich set of classes for XML manipulation in several namespaces that start with System.Xml. One of the most confusing aspects of using XML with .NET is deciding which combination of classes you should use. Many of them provide similar functionality in a slightly different way, optimized for specific scenarios or for compatibility with specific standards. The majority of the examples you ll explore use the types in the core System.Xml namespace. The classes here allow you to read and write XML files, manipulate XML data in memory, and even validate XML documents. In this chapter, you ll look at the following options for dealing with XML data: Reading and writing XML directly, just like you read and write text files using XmlTextWriter and XmlTextReader Dealing with XML as a collection of in-memory objects, such as XmlDocument and XmlNode Binding to the XmlDataSource to display XML information with minimum fuss Dealing with XML as an interface to relational data using the XmlDataDocument class

LinearLayout is a box model, in which widgets or child containers are lined up in a column or row, one after the next. This works in a similar manner to FlowLayout in Java/Swing, and vbox and hbox in Flex and XUL. Flex and XUL use the box as their primary unit of layout. If you want, you can use LinearLayout in much the same way, eschewing some of the other containers. Getting the visual representation you want is mostly a matter of identifying where boxes should nest and which properties those boxes should have, such as their alignment in relation to other boxes.

As we described earlier, assigning responsibilities to each class involves giving your class some personality, but it s also possible for a class to become overallocated and end up with perhaps a little too much personality Dan Rawsthorne (a former ICONIX instructor) once summarized the responsibility-driven thought process to Doug as follows: If you think of your objects (or classes) as people, then the set of behaviors (operations) that they are responsible for gives them a sort of personality We want to watch out for schizophrenic objects (that is, objects with split or multiple personalities) because an object should be focused on a cohesive, related set of behaviors A class with a split personality or multiple personalities is a class that has more than one responsibility.
