The client side representation of a vector layer.

org.geomajas.layer.VectorLayer
A layer which contains vector data.
It hold all the elements that belong to a layer within the bounds determined by the client's view. It is able to manipulate the objects which are represented as features on the map. @author Pieter De Graef @author Jan De Moerloose @since 1.6.0
