/**
 * Output a debug message at the output stream sepcified in the init()
 * method. This method is very lightweight if debugging is turned off, since
 * it will return immediately. However, the caller should be aware that
 * if the argument to Debug.trace() is an object whose toString() is
 * expensive, that this toString() will still be called in any case.
 * In such a case, it is wise to wrap the Debug.trace like this:
 *
 * <pre>// w  w  w.jav  a 2s.  com
 * if (Debug.on()) {
 *     Debug.trace(&quot;obj is: &quot; + obj);
 * }
 * </pre>
 *
 * @param level the message level. If this is >= than the currently set
 *            level (set with setLevel() ), the message is printed
 * @param t the message to print
 * @param ignoreStack when walking the stack to determine the
 *            location of the method that called the trace() method,
 *            ignore any classes with this string in. Can be null
 * @param printCaller if true, (and if static mShowCaller is true)
