<div class="info">
|
|
<b>ol.interaction.Splitter</b> is an interaction that acts as a split feature agent while editing vector features (LineString).
|
|
<br/>
|
|
The features are cloned. The interaction fires a <i>beforesplit</i> and <i>aftersplit</i> event on the source.
|
|
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 />
|
|
<b>TODO:</b> Split with more than one feature (when moving nodes)
|
|
<br />
|
|
<b>NB:</b> If you look to an interaction that split a linestringjust on clicking a point on the feature, look at <a href="map.interaction.split.html">ol.interaction.Split</a>.
