41 /** A special {@link ScannerState} implementation that ignores all child
42  * elements.
43  *
44  * <p>Consider the call hierarchy:
45  * <code>
46  * methodInvocation
47  *   objectInstantiation
48  *     classResolution*
49  *       objectInstantiation
50  *         classResolution
51  * </code>
52  * </p>
53  *
54  * <p>When the ignoring state is active one can filter the elements of
55  * one level. One has to set up the state machine that a transition
56  * via "class resolution" from a state that was reached via "object
57  * instantation" reaches an <code>IgnoringScannerState</code>.</p>
58  *
59  * <p>Setting the default successor of a <code>IgnoringScannerState</code>
60  * to itself causes all elements of the call hierarchy to be skipped
61  * until another state is reached by going back.</p>
