| <h1>Override Indicators |
| </h1> |
| <p>‘Override Indicators’ are markers that display special decoration icons |
| to indicate methods that override or implement other methods from a super-type's |
| class/interface.</p> |
| <p>The override indicators will be displayed as triangles in the marker |
| bar (the vertical ruler to the left of the editor) next to the method's |
| definition.</p> |
| <p class="picture"><img src="override_indicators.png" alt="Override Indicators" title="Override Indicators" style="border: none;" width="428" height="164" border="0"></p> |
| <p>Green triangles indicate an overridden method, while a white triangle |
| indicates an implemented method.</p> |
| <p> </p> |
| <p>Hovering over a triangle displays a tool-tip that reveals the overridden |
| or implemented method's super-type. Clicking the triangle will open the |
| type in an editor.</p> |
| <p class="picture"><img src="override_indicator_tooltip.png" alt="Override Indicators Tooltip" title="Override Indicators Tooltip" style="border: none;" width="294" height="46" border="0"></p> |
| <p style="font-weight: bold;">Note:</p> |
| <p>Markers will not be displayed if the methods do not comply with the |
| overriding rules.</p> |
| <p>These are as follows:</p> |
| <ul type="square"> |
| <li><p>You cannot override a non-static method with a static method.</p></li> |
| <li><p>The overriding method must not be more restrictive than the |
| overridden method</p></li> |
| <li><p>‘private’ methods are not inherited and cannot be overridden.</p></li> |
| </ul> |
| <p class="ListBullet1"> </p> |
| <h5>Override Indicators Preferences</h5> |
| <p>The display preferences for the override indicators can be configured |
| from the <a href="../../plugins_root/org.eclipse.platform.doc.user/reference/ref-22.htm">Annotations |
| preferences page</a> (<span style="font-weight: bold;"><b>Window | Preferences |
| | General | Editors | Text Editors | Annotations</b></span>).</p> |
| <p>Select the Override Indicators (org.eclipse.php.ui.overrideIndicator) |
| option to configure the Override Indicators for PHP.</p> |
