| Previously, <a class="otjldlink" href="http://www.objectteams.org/def/1.3/s1.html#s1.5.e">OTJLD §1.5(e)</a> |
| was inconsistent between its first and second sentences. |
| The first sentence defines the general precendence between <code class="keyword">super</code> and <code class="keyword">tsuper</code>, |
| which will remain unchanged. |
| However, the precendence among different tsupers has been adjusted as demonstrated using this example: |
| <div class="listbox"><div class="listing"><pre><code class="keyword">public team class</code> <font color="blue">Team0</font> { |
| <code class="keyword">protected team class</code> <font color="darkblue">InnerTeamA</font> { |
| <code class="keyword">protected class</code> <b>Role</b> { |
| <code class="keyword">public void</code> rm() { ... } |
| } |
| <code class="keyword">public void</code> tm() { ... } |
| } |
| <code class="keyword">protected team class</code> InnerTeamB <code class="keyword">extends</code> <font color="darkblue">InnerTeamA</font> { |
| <code class="keyword">protected class</code> <b>Role</b> { |
| <code class="keyword">public void</code> rm() { ... } |
| } |
| <code class="keyword">public void</code> tm() { ... } |
| } |
| } |
| <code class="keyword">public team class</code> <font color="blue">Team1 <code class="keyword">extends</code> Team0</font> { |
| <code class="keyword">protected team class</code> <font color="darkblue">InnerTeamA</font> { |
| <code class="keyword">protected class</code> <b>Role</b> { |
| <code class="keyword">public void</code> rm() { ... } |
| } |
| <code class="keyword">public void</code> tm() { ... } |
| } |
| <code class="keyword">protected team class</code> <font color="darkblue">InnerTeamB</font> <code class="keyword">extends</code> <font color="darkblue">InnerTeamA</font> { |
| <font color="green">// details inherited from Team1.InnerTeamA and Team0.InnerTeamB</font> |
| } |
| } |
| </pre></div></div> |
| When invoking <code>tm()</code> on an instance of <code>Team1.InnerTeamB</code> two implementation are |
| candidates for execution:<ul> |
| <li><code>Team1.InnerTeamA.tm()</code></li> |
| <li><code>Team0.InnerTeamB.tm()</code>,</li></ul> |
| from which <a class="otjldlink" href="http://www.objectteams.org/def/1.3/s1.html#s1.5.e">OTJLD §1.5(e)</a> |
| selects <code>Team0.InnerTeamB</code>.<br /> |
| Correspondingly, when invoking <code>rm()</code> on an instance of <code>Team1.InnerTeamB.R</code> two implementation are |
| candidates for execution:<ul> |
| <li><code>Team1.InnerTeamA.Role.rm()</code></li> |
| <li><code>Team0.InnerTeamB.Role.rm()</code>,</li></ul> |
| from which <a class="otjldlink" href="http://www.objectteams.org/def/1.3/s1.html#s1.5.e">OTJLD §1.5(e)</a> |
| now selects <code>Team0.InnerTeamB.Role</code>, consistent with the above. |

| <td><p>When a role uses a callout <code class="keyword">set</code> to field with decapsulation this may be considered more severe |
