+ * Common functionality used for testing when implementing various Handlers and

+ * expected errors or the like. Likely used to implement testing wrapper classes
+ * for things like javax.xml.transform.ErrorListener and
+ * org.xml.sax.ErrorHandler</p>
+ * <p>
+ * The best description for this class can be seen in an example; see
+ * trax.LoggingErrorHandler.java for one.</p>

+     * see an item that matches, or to call checkFail when we get an unexpected
+     * item. Generally, we only call check* methods when:
+     * <ul>
+     * <li>containsString is not set, reset, or is ITEM_DONT_CARE, we do nothing
+     * (i.e. never call check* for this item)</li>

+     * the contents of any item if it occurs</li>
+     * <li>containsString is anything else, we will grab a String representation
+     * of every item of that type that comes along, and if the containsString is
+     * found, case-sensitive, within the handled item's string, call checkPass,
+     * otherwise call checkFail</li>

+     * specific type, and then will reset validation for that event type. This
+     * is because many events may be raised in between the time that a calling
+     * Test class could tell us of the 'next' expected event.
