public class NetMapGraphicLoader
extends MMLGraphicLoader
implements NetMapListener, NetMapConstants

The NetMapGraphicLoader is a component that can listen to a NetMapConnector, receive and interpret NetMapEvents, and draw the resulting network on the map. The NetMapConnector does all the heavy work, the NetMapGraphicLoader serves as an interface to get OMGraphics on the map.

The easiest way to use this class is to create it with the NetMapConnector and add it to the LayerHandler or MapHandler. If the NetMapConnector is going to be created by another object for application design reasons, just create a NetMapConnectionHandler and add it to the MapHandler, and then add the NetMapConnector to the MapHandler, too. The NetMapConnectionHandler will create a NetMapGraphicLoader for the NetMapConnector. Make sure a GraphicLoaderConnector is also in the MapHandler, too, because it will create a GraphicLoaderPlugIn/PlugInLayer for the NetMapGraphicLoader.

Constructor Detail

NetMapGraphicLoader

public NetMapGraphicLoader()

Constructor for the NetMapGraphicLoader, you still have to set the NetMapConnector.

NetMapGraphicLoader

public NetMapGraphicLoader(NetMapConnector nmc)

Constructor for the NetMapGraphicLoader that sets the NetMapConnector.

Parameters:

nmc - the NetMapConnector to listen to.

Method Detail

setNetMapConnector

public void setNetMapConnector(NetMapConnector nmc)

Set the NetMapConnector to listen to. This method will add the NetMapGraphicLoader to the NetMapConnector as a NetMapListener. If there is already a NetMapConnector set in this NetMapGraphicLoader, then this method will disconnect from the current NetMapConnector, and reconnect with the new one if it isn't null.

getNetMapConnector

public NetMapConnector getNetMapConnector()

Get the current NetMapConnector.

catchEvent

public void catchEvent(NetMapEvent nme)

NetMapListener method, called by the NetMapConnector.

Specified by:

catchEvent in interface NetMapListener

processEventProperties

protected void processEventProperties(java.util.Properties eventProps)

Process a NetMapEvent Properties object, which means that a Properties object, representing an event from the NetMap server, is evaluated and used to modify the NodeCache and LineCache accordingly.

Parameters:

eventProps - the properties from a NetMapEvent.

getOMList

protected OMGraphicList getOMList()

Internal method used to create a single OMGraphicList from the NodeCache and the LineCache.

getGUI

public java.awt.Component getGUI()

Called by the GraphicLoaderPlugIn, the GUI is provided from the NetMapConnector.

Specified by:

getGUI in interface GraphicLoader

Overrides:

getGUI in class AbstractGraphicLoader

getName

public java.lang.String getName()

Needed to fill in a GUI with a receiver's name, to enable the user to send a graphic to a specific object. Should be a pretty name, suitable to let a user know what it is.

Specified by:

getName in interface GraphicLoader

Overrides:

getName in class AbstractGraphicLoader

manageGraphics

public void manageGraphics()

The inherited AbstractGraphicLoader method, that sends the current OMGrapicList to the receiver.

Specified by:

manageGraphics in class AbstractGraphicLoader

See Also:

OMGraphicHandler.setList(OMGraphicList)

mouseMoved

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

Invoked when the mouse button has been moved on a component (with no buttons down).

Specified by:

mouseMoved in interface MapMouseListener

Overrides:

mouseMoved in class MMLGraphicLoader

Parameters:

e - MouseEvent

Returns:

true if the listener was able to process the event.
