<b>ol/interaction/ModifyFeature</b> is an interaction for modifying feature geometries,
|
|
similar to the core <i>ol/interaction/Modify</i>.
|
|
<br/>
|
|
The interaction is more suitable to use to handle feature modification:
|
|
only features concerned by the modification are passed to the events
|
|
(instead of all feature with ol/interaction/Modify)
|
|
<ul>
|
|
<li>
|
|
the <i>modifystart</i> event is fired before the feature is modified (no point still inserted)
|
|
</li>
|
|
<li>
|
|
the <i>modifyend</i> event is fired after the modification
|
|
</li>
|
|
<li>
|
|
it fires a <i>modifying</i> event
|
|
</li>
|
|
</ul>
