	Method		Defined by
		addMapListeners():void Adds listeners for ExtentEvent.EXTENT_CHANGE, ZoomEvent.ZOOM_START, ZoomEvent.ZOOM_UPDATE and ZoomEvent.ZOOM_END.	Layer
		extentChangeHandler(event:ExtentEvent):void When an EXTENT_CHANGE event occurs, this calls invalidateLayer();	Layer
		hideHandler(event:FlexEvent):void When the layer is hidden (visible is set to false), this calls removeMapListeners().	Layer
		invalidateLayer():void Subclasses should call this whenever they would like to have updateLayer() called on them.	Layer
		loadMapImage(loader:Loader):void Subclasses must override this method.	DynamicMapServiceLayer
		removeAllChildren():void Removes all the layers children.	Layer
		removeMapListeners():void Removes the four event listeners added by addMapListeners();	Layer
		setLoaded(value:Boolean):void Subclasses must call this when they've loaded all their properties and are ready to load their content.	Layer
		showHandler(event:FlexEvent):void When the layer is shown (visible is set to true), this calls addMapListeners() and invalidateLayer().	Layer
		toScreenX(mapX:Number):Number Converts the x-coordinate of map point to a screen point.	Layer
		toScreenY(mapY:Number):Number Converts the y-coordinate of map point to a screen point.	Layer
		updateLayer():void Subclasses must override this method.	Layer
		zoomEndHandler(event:ZoomEvent):void Finishes the zoom animation.	Layer
		zoomStartHandler(event:ZoomEvent):void Prepares the zoom animation by taking a bitmap of the layer.	Layer
		zoomUpdateHandler(event:ZoomEvent):void Redraws the bitmap of the layer.	Layer
