CodegenPrinter

public class Printer
extends Object

Manages printing of indented source code. Line numbers start at 1 and increase by 1 every time nl() is called. Note that the proper use of this class requires calling nl() at the START of every line (thanks, Harold!), which make indentation much easier to manage. For example, an if statement can be printed as nl().p( "if (expr) {" ).in() ; nl().p( "stmt" ).out() ; nl().p( "} else {" ).in() ; nl().p( "stmt" ).out() ;
