- All Implemented Interfaces:
- java.awt.event.ActionListener, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.util.EventListener, java.awt.image.ImageObserver, MapMouseListener, java.awt.MenuContainer, ProjectionListener, ProjectionPainter, PropertyConsumer, java.io.Serializable
- public class CacheLayer
- extends Layer
- implements java.awt.event.ActionListener, MapMouseListener
A Layer that gets it's graphics from a URL containing a serialized
OMGraphicList. This layer does respond to gesturing on the
graphics, but doesn't do anything. You can extend this class to be
more useful to you. It has one property that needs to be set in the
properties file:
# CacheLayer property:
# The layer should figure out
whether it's a file or URL.
cachelayer.cacheFile=

protected java.net.URL cacheURL
- URL to read data from. This data will be in the form of a
serialized stream of OMGraphics.
omgraphics
protected OMGraphicList omgraphics
- A list of graphics to be painted on the map.

getMouseModeServiceList()
mouseMoved
public boolean mouseMoved(java.awt.event.MouseEvent e)

requested mouse modes is active.
Tries to locate a graphic near the mouse, and if it is found,
it is highlighted and the Layer is repainted to show the
highlighting.

mouseMoved
in interface MapMouseListener
- See Also:
getMouseModeServiceList()
getMapMouseListener
public MapMouseListener getMapMouseListener()
- Returns self as the

would prefer to delegate MapMouseEvent
s, it
could return the delegate from this method instead.
