public class Stringify

extends Object

Stringify safely prints object references to strings: catching errors, eliding long collections, etc., and printing classes, arrays, and strings in a more recognizeable syntax than their default toString method provides.

printToString

public static String printToString(Object obj)

printToString -- safely prints object to string: prints null as "null", adds quotes around strings, only prints up to printLength array, java.util.Collection, java.util.Map, or java.util.Set elements. Prints classes as ClassName.class, and array classes as ComponentClass[].class. Safely calls toString() on other objects, catching throws and returning an alternate string containing the class of the object and the thrown exception name.
