<div class="info">
|
|
<b>ol.interaction.Split</b> is an interaction to split linestrings by clicking on a point on the feature (ol.geom.LineString only).
|
|
<br/>
|
|
The feature is cloned. The interaction fires a beforesplit and aftersplit event.
|
|
You can listen to the event on the interaction itself or on the source of the splitted feature.
|
|
<br/>
|
|
The sources provided to the interaction must have a spatial index to be splitable (configured with useSpatialIndex set to true).
|
|
<br />
|
|
<br/>
|
|
NB: If you look to a split feature agent while editing vector features, look at <a href="map.interaction.splitter.html">ol.interaction.Splitter</a>.
