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