/** 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>
