<h1>Binding markers</h1>
<p><b>Binding</b> <a href="/help/topic/org.eclipse.platform.doc.user/concepts/concepts-11.htm">
markers</a> are OT/J specific annotations on the vertical ruler (marker bar) left of the
extended <a href="editor.html">Java Editor</a>. These markers come in three flavors:
<li>A <b>playedBy marker</b> <img src="../images/playedBy_obj.gif"> signals that one or more roles is bound
to the current class using <code class="keyword">playedBy</code> (<a href="otjld/def/s2.html#s2.1"><img src="../images/ot_paragraph.png"> 2.1</a>).</li>
<li>A <b>callin marker</b> <img src="../images/callinbinding_obj.gif"> signals that one or more callin bindings
(<a href="otjld/def/s4.html#s4"><img src="../images/ot_paragraph.png"> 4</a>) affect the given base method.
<li>A <b>callout marker</b> <img src="../images/callout_marker.gif"> signals that one or more callout bindings (<a href="otjld/def/s3.html#s3"><img src="../images/ot_paragraph.png"> 3</a>)
affect the given base method <b>and</b> that these callout bindings apply decapsulation
(<a href="otjld/def/s3.html#s3.4"><img src="../images/ot_paragraph.png"> 3.4</a>)
&mdash;&nbsp;(callout bindings <em>without</em> decapsulation are ranked like regular method calls
and thus not considered relevant for marking in the ruler).

Aside from raising awareness of these bindings, the markers can also be used to directly
navigate to the corresponding role or callin/callout binding.
When right clicking on a binding marker a pop-up menu will open which contains
a corresponding submenu <span class="ui">OT/J bound roles</span>, or <span class="ui">OT/J callin bindings</span>, or <span class="ui">OT/J callout decapsulation</span>.
This submenu in turn holds all bindings relevant at the current position,
sorted by teams.

Binding markers are enabled/disabled globally on the <span class="ui">Object Teams</span> preference page.<br>
Detailed configuration is possible via <span class="ui">Window->Preferences->General->Editors->Text Editors->Annotations</span>
