## com.bbn.openmap.layer.dted
Class DTEDFrameCacheLayer

    java.lang.Object
      java.awt.Component
          java.awt.Container
              javax.swing.JComponent
                  com.bbn.openmap.Layer
                      com.bbn.openmap.layer.OMGraphicHandlerLayer
                          com.bbn.openmap.layer.dted.DTEDFrameCacheLayer

All Implemented Interfaces:
  java.awt.event.ActionListener, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, DTEDConstants, java.util.EventListener, GestureResponsePolicy, java.awt.image.ImageObserver, MapMouseListener, java.awt.MenuContainer, ProjectionListener, ProjectionPainter, PropertyConsumer, java.io.Serializable

public class DTEDFrameCacheLayer
extends OMGraphicHandlerLayer
implements java.awt.event.ActionListener, MapMouseListener, java.io.Serializable, DTEDConstants

The DTEDFrameCacheLayer fills the screen with DTED data. To view the DTED iamges, the projection has to be set in an ARC projection, which OpenMap calls the CADRG or LLXY projection. In Gesture mode, clicking on the map will cause the DTEDFrameCacheLayer to place a point on the window and show the elevation of that point. The Gesture response is not dependent on the scale or projection of the screen.

The DTEDFrameCacheLayer uses the DTEDCacheHandler to get the images it needs. The DTEDFrameCacheLayer receives projection change events, and then asks the cache handler for the images it needs based on the new projection. The DTEDFrameCacheLayer also relies on properties to set its variables, such as the dted frame paths (there can be several at a time), the opaqueness of the frame images, number of colors to use, and some other display variables. The DTEDFrameCacheLayer properties look something like this:

NOTE: Make sure your DTED file and directory names are in lower case. You can use the com.bbn.openmap.layer.rpf.ChangeCase class to make modifications if necessary.

    public void removed(java.awt.Container cont)

  Called when the layer is no longer part of the map.

  Overrides:
    `removed` in class `Layer`
  Parameters:
    `cont` - Container

### findAndInit

    public void findAndInit(java.lang.Object someObj)

  Description copied from class: `Layer`
  This method is called by the findAndInit(Iterator) method, once for every object inside the iterator. It's here to allow subclasses a way to receive objects and still let the super classes have a shot at the object. So, you can override this method can call super.findAndInit(obj), or override the findAndInit(Iterator) method and call super.findAndInit(obj). Whatever.

  Overrides:
    `findAndInit` in class `Layer`

### findAndUndo

    public void findAndUndo(java.lang.Object someObj)

  Description copied from class: `Layer`
  This is the method that does the opposite as the findAndInit(Object). Lets you call super classes with objects that need to be removed.

  Overrides:
    `findAndUndo` in class `Layer`

### prepare

    public OMGraphicList prepare()

  Prepares the graphics for the layer. This is where the getRectangle() method call is made on the dted.

  Occasionally it is necessary to abort a prepare call. When this happens, the map will set the cancel bit in the LayerThread, (the thread that is running the prepare). If this Layer needs to do any cleanups during the abort, it should do so, but return out of the prepare asap.

  Overrides:
    `prepare` in class `OMGraphicHandlerLayer`

### paint

    public void paint(java.awt.Graphics g)

  Paints the layer.

  Overrides:
    `paint` in class `OMGraphicHandlerLayer`
  Parameters:
    `g` - the Graphics context for painting

### getDtedLevel

    public int getDtedLevel()

  Get the value set for which DTED level is being used, 0-2.

### setDtedLevel

    public void setDtedLevel(int level)

### getKillCache

    public boolean getKillCache()

  Get whether the cache will be killed when the layer is removed from the map.

### setKillCache

    public void setKillCache(boolean kc)

### getGUI

    public java.awt.Component getGUI()

  Creates the interface palette.

  Overrides:
    `getGUI` in class `Layer`
  Returns:
    java.awt.Component or null

### getMapMouseListener

    public MapMouseListener getMapMouseListener()

  Description copied from class: `OMGraphicHandlerLayer`
  Query asked from the MouseDelegator for interest in receiving MapMouseEvents. This returns a MapMouseInterpreter that has been told to listen for events from the MapMouseModes in setMouseModeIDsForEvents().

  Overrides:
    `getMapMouseListener` in class `OMGraphicHandlerLayer`

### getMouseModeServiceList

    public java.lang.String[] getMouseModeServiceList()

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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.

  NOTE: We have noticed that this method can sometimes be erroneously invoked. It seems to occur when a light-weight AWT component (like an internal window or menu) closes (removes itself from the window hierarchy). A specific OpenMap example is when you make a menu selection when the MenuItem you select is above the MapBean canvas. After making the selection, the mouseClicked() gets invoked on the MouseDelegator, which passes it to the appropriate listeners depending on the MouseMode. The best way to avoid this problem is to not implement anything crucial in this method. Use a combination of `mousePressed()` and `mouseReleased()` instead.

  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)

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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)

  Description copied from interface: `MapMouseListener`
  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()

  Description copied from interface: `MapMouseListener`
  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`
