Vector Layer class

The Vector Layer, by itself, is a layer like the other layers we've discussed so far—but to really get the most out of it, we'll be working with other classes.

To even get a basic example working (like the first one in this chapter), we make use of a few other classes. Specifically, the Vector class makes use of the Feature class to show objects on the layer. But for the Feature class to work, it needs to use the Geometry class to create geometry objects. Therefore, the actual vector objects in your vector layers are Feature objects which are composed of Geometry objects—we'll cover all that soon.

Before we do that though, let's cover the Vector Layer class itself. We'll first go over the properties of the Vector class, and then the methods (in a similar manner to Chapter 3).

OpenLayers.Layer.Vector properties

Let's go over the properties that the Vector class contains. Some of them are instantiated objects from other classes, which will be covered later in this chapter.
