In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The Database.merge and merge DML statements support merging of accounts, leads, and contact records."

A block of code is set as follows:

public class ContestantService{

  public class RaceRetirement{
    public Id contestantId;
    public String reason;
  }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public class ProvisionalResult{
  public Integer racePosition {get; set;}
  public Id contestantId {get; set;}
  public String contestantName {get; private set;}
}

Any command-line input or output is written as follows:

ant package.installdemo

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "You can see the current storage utilization from the Custom Settings page under Setup"
