/** A special {@link ScannerState} implementation that ignores all child
 * elements.
 * 
 * <p>Consider the call hierarchy:
 * <code>
 * methodInvocation
 *   objectInstantiation
 *     classResolution*
 *       objectInstantiation
 *         classResolution
 * </code>
 * </p>
 * 
 * <p>When the ignoring state is active one can filter the elements of
 * one level. One has to set up the state machine that a transition
 * via "class resolution" from a state that was reached via "object
 * instantation" reaches an <code>IgnoringScannerState</code>.</p>
 * 
 * <p>Setting the default successor of a <code>IgnoringScannerState</code>
 * to itself causes all elements of the call hierarchy to be skipped
 * until another state is reached by going back.</p>
