Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Let's say that we have a Rectangle base class with two separate SetWitdh and SetHeight methods."

A block of code is set as follows:

Rectangle rect = new Square();
rect.setWidth(10);
rect.setHeight(5);
Assert.Equal(50, CalculateArea(rect));

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "I defined the MessageBroker as an ABB, and the three rectangles on the right are solutions that fulfil this need."
