Specified by:

getLayer in interface ProjectionChangePolicy

projectionChanged

public void projectionChanged(ProjectionEvent pe)

Description copied from interface: ProjectionChangePolicy

The method that is called when the projection changes. The ProjectionChangePolicy should modify the OMGraphicList and do other functions as dictated by the policy, like starting threads to gather data and generating new OMGraphics for the layer.

Specified by:

projectionChanged in interface ProjectionChangePolicy

setLayer

public void setLayer(OMGraphicHandlerLayer layer)

Description copied from interface: ProjectionChangePolicy

Set the OMGraphicHandlerLayer to work with.

Specified by:

setLayer in interface ProjectionChangePolicy

workerComplete

public void workerComplete(OMGraphicList aList)

Description copied from interface: ProjectionChangePolicy

The method that gets called when the SwingWorker thread finishes. The OMGraphicList is what is getting returned from the prepare() method on the layer, so it's most likely that this list should be set on the layer.
