while (i>0) { i--; j++; }instead of
while (i>0) { i --; j++;}if a maximum line width of 15 characters is chosen. The frontend to the Pretty-Printer is the {@link de.uka.ilkd.pp.Layouter} class. You may configure what happens with the output by implemenenting the {@link de.uka.ilkd.pp.Backend} interface, or by using one of the standard implementations {@link de.uka.ilkd.pp.StringBackend} and {@link de.uka.ilkd.pp.WriterBackend}.
A particularly common use is to print arbitrary data structures like with the {@link java.lang.Object#toString()} method, but formatted using whitespace and indentation. This is supported by the {@link de.uka.ilkd.pp.DataLayouter} class, which provides for standard layouts for collections, arrays, and maps, but also allows new classes to implement the {@link de.uka.ilkd.pp.PrettyPrintable} interface to specify their preferred layout. @author Martin Giese
