How to remove a linestring from MultiLineString in OpenLayers?

Question

I can append lineStrings with appendLineString method. But how to remove them? I tried to splice them from the getLineStrings array, but without success.

The closest I came was:

//multiLineString is my ol.geom.MultiLineString object
multiLineString.setCoordinates([]);

Thanks

This works for me:

var multi = new ol.geom.MultiLineString([[[1,2],[2,3],[1,4]],[[2,1],[3,2],[4,1]]]);
var singles = multi.getLineStrings(); //returns an array of 2 LineStrings
singles.splice(0,1);
multi.setLineStrings(singles);

multi.getLineStrings(); //returns a single LineString
