Examples of ILayerListener

org.eclipse.nebula.widgets.nattable.layer.ILayerListener
Object interested in receiving events related to a {@link ILayer}.
org.locationtech.udig.project.ILayerListener
Listens to changes on this layer.
This method is similar, but not identical to adding an "adapter" the the layer. The only reason this may not be identical is the presense of LayerDecorator, when working with a wrapped layer changes that take place only on the decorator will not be available via EMF adapaters.

Responsibilities:
- Provide callbacks when layer modifications occur
- The LayerEvent can be used to communicate the nature of the change
