public class EarthquakeLayer
extends OMGraphicHandlerLayer
implements MapMouseListener

Get data about recent earthquakes from the USGS finger sites and display it.

Debugging information is printed when the OpenMap Viewer is launch with -Ddebug.earthquake flag.

 
 
   # Properties for the Earthquake Layer
   earthquake.sites=<finger site> <finger site> ...
   # in seconds
   earthquake.queryinterval=300
 
 
 
NOTE: I'm not sure this layer works anymore, probably hasn't for some time since the finger sites no longer provide data AFAIK. Leaving this layer in the package as another example.

The layer GUI.

Constructor Detail

EarthquakeLayer

public EarthquakeLayer()
Construct an EarthquakeLayer.

Method Detail

prepare

public OMGraphicList prepare()
Fetch data from finger sites, if needed, generate the OMGraphics with the current projection regardless.

Overrides:
prepare in class OMGraphicHandlerLayer

needToRefetchData

protected boolean needToRefetchData()
Fetches data if it hasn't been fetched in a while.


generateGraphics

protected OMGraphicList generateGraphics()
Create the graphics.


parseData

protected void parseData(java.util.Vector data)
Parse the finger site data.

Parameters:
data - Vector

getEarthquakeData

protected java.util.Vector getEarthquakeData()
Get the earthquake data from the USGS. Should be called in a SwingWorker thread, or you will freeze the application.

Returns:
Vector containing information from the websites.

getGUI

public java.awt.Component getGUI()
Gets the gui controls associated with the layer.

Overrides:
getGUI in class Layer
Returns:
Component

getMapMouseListener

public MapMouseListener getMapMouseListener()
Returns the MapMouseListener object that handles the mouse events.

Overrides:
getMapMouseListener in class OMGraphicHandlerLayer
Returns:
the MapMouseListener for the layer, or null if none

getMouseModeServiceList

public java.lang.String[] getMouseModeServiceList()
Return a list of the modes that are interesting to the MapMouseListener. The source MouseEvents will only get sent to the MapMouseListener if the mode is set to one that the listener is interested in. Layers interested in receiving events should register for receiving events in "select" mode:
 return new String[] { SelectMouseMode.modeID };
 

Specified by:
getMouseModeServiceList in interface MapMouseListener
Returns:
String[] of modeID's
See Also:
NavMouseMode.modeID, SelectMouseMode.modeID, NullMouseMode.modeID

mousePressed

public boolean mousePressed(java.awt.event.MouseEvent e)
Invoked when a mouse button has been pressed on a component.

Specified by:
mousePressed in interface MapMouseListener
Parameters:
e - MouseEvent
Returns:
true if the listener was able to process the event.

mouseReleased

public boolean mouseReleased(java.awt.event.MouseEvent e)
Invoked when a mouse button has been released on a component.

Specified by:
mouseReleased in interface MapMouseListener
Parameters:
e - MouseEvent
Returns:
true if the listener was able to process the event.

mouseClicked

public boolean mouseClicked(java.awt.event.MouseEvent e)
Invoked when the mouse has been clicked on a component. The listener will receive this event if it successfully processed mousePressed(), or if no other listener processes the event. If the listener successfully processes mouseClicked(), then it will receive the next mouseClicked() notifications that have a click count greater than one.

Specified by:
mouseClicked in interface MapMouseListener
Parameters:
e - MouseEvent
Returns:
true if the listener was able to process the event.

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent e)
Invoked when the mouse enters a component.

Specified by:
mouseEntered in interface MapMouseListener
Parameters:
e - MouseEvent

mouseExited

public void mouseExited(java.awt.event.MouseEvent e)
Invoked when the mouse exits a component.

Specified by:
mouseExited in interface MapMouseListener
Parameters:
e - MouseEvent

mouseDragged

public boolean mouseDragged(java.awt.event.MouseEvent e)
Invoked when a mouse button is pressed on a component and then dragged. The listener will receive these events if it successfully processes mousePressed(), or if no other listener processes the event.

Specified by:
mouseDragged in interface MapMouseListener
Parameters:
e - MouseEvent
Returns:
true if the listener was able to process the event.

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
Parameters:
e - MouseEvent
Returns:
true if the listener was able to process the event.

mouseMoved

public void mouseMoved()
Handle a mouse cursor moving without the button being pressed. This event is intended to tell the listener that there was a mouse movement, but that the event was consumed by another layer. This will allow a mouse listener to clean up actions that might have happened because of another motion event response.

Specified by:
mouseMoved in interface MapMouseListener

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)
Set the properties of the EarthquakeLayer.

Specified by:
setProperties in interface PropertyConsumer
Overrides:
setProperties in class OMGraphicHandlerLayer
Parameters:
prefix - String
props - Properties

getProperties

public java.util.Properties getProperties(java.util.Properties props)
Get the associated properties object.

Specified by:
getProperties in interface PropertyConsumer
Overrides:
getProperties in class OMGraphicHandlerLayer
Parameters:
props - a Properties object to load the PropertyConsumer properties into. If props equals null, then a new Properties object should be created.
Returns:
Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

getProperties

public java.util.Properties getProperties(java.lang.String prefix,
                                          java.util.Properties props)
Get the associated properties object. This method creates a Properties object if necessary and fills it with the relevant data for this layer. Relevant properties for EarthquakeLayers are the sites to retrieve earth quake data from, and the interval in milliseconds (see class description.)


getPropertyInfo

public java.util.Properties getPropertyInfo(java.util.Properties info)
Supplies the propertiesInfo object associated with this EarthquakeLayer object. Contains the human readable descriptions of the properties and the initPropertiesProperty (see Inspector class.)

Specified by:
getPropertyInfo in interface PropertyConsumer
Overrides:
getPropertyInfo in class OMGraphicHandlerLayer
Parameters:
info - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.
Returns:
Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.
