Example of setting a layer source after construction.
Typically, the source for a layer is provided to the layer constructor.
If you need to set a layer source after construction, this can be
done with the layer.setSource()
method.
The layer in the map above is constructed with no source. Use the links below to set/unset the layer source. A layer is not rendered until its source is set.
See the lazy-source.js source for details on how this is done.
