Class VectorLayer<T>

java.lang.Object
io.jmix.mapsui.component.layer.VectorLayer<T>
All Implemented Interfaces:
Layer, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware
public class VectorLayer<T> extends Object
A layer containing geo-objects (entities having a property of a Geometry type.

This layer acts as a connector between the data (geo-objects provided by VectorLayerItems interface implementation) and the map UI component. It carries the data along with some additional information on how the geo-objects should be displayed on a map (styles, content of popup info windows).
