| 16 | <h1 align="center">Call hierarchy extended for OT/J<a name="callhierarchy"></a></h1> |
| 17 | <p> |
| 18 | The purpose of the Java call hierarchy view is to statically display all potential |
| 19 | control flows originating from or leading to a specific program element. |
| 20 | Since callout and callin method bindings in OT/J introduce new kinds of control flows, |
| 21 | it is only appropriate to also visualize the control flows induced by such method bindings. |
| 22 | </p> |
| 23 | <p> |
| 24 | Whenever a given method can be invoked via a <b>callout method binding</b>, |
| 25 | the call hierarchy shows a <img src="../images/calloutbinding_obj.gif"> callout node. |
| 26 | Here all calls to the corresponding role method will be forwarded to the base method. |
| 27 | </p> |
| 28 | <p> |
| 29 | Whenever a <b>callin method binding</b> may intercept a given control flow, |
| 30 | a <img src="../images/callinbindingreplace_obj.gif"> callin node is shown. |
| 31 | Note, that a callin control flow is only taken at runtime, |
| 32 | if the enclosing team is active and no guard predicate evaluates to false. |
