All Implemented Interfaces:

InfoDisplayListener, LayerStatusListener, MapMouseListener, ProjectionListener, ProjectionPainter, PropertyConsumer, java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener

public class ScaleFilterLayer
extends Layer
implements InfoDisplayListener, LayerStatusListener, java.beans.PropertyChangeListener, MapMouseListener

An OpenMap Layer that encapsulates other layers and acts as a scale filter. It will delegate responsibility to one of several layers depending on the scale.

To use this layer, list it as a layer in the openmap.properties file in the openmap.layers properties, as you would add any other layer. Then, add these properties to the openmap.properties file. The layers added to the ScaleFilterLayer do not get added to the openmap.layers property, but instead get added to the scaledFilterLayer.layers property listed here. Then, the properties for these layers are added to the openmap.properties file like any other layer.

 The properties for this layer look like this:
 
 scaledFilterLayer.class=com.bbn.openmap.layer.ScaleFilterLayer
 scaledFilterLayer.prettyName=<Pretty name used on menu>
 # List 2 or more layer prefixes, larger scale layers first
 scaledFilterLayer.layers=layer_1 layer_2 layer_3 ...
 # List the transition scales to switch between layers
 scaledFilterLayer.transitionScales= (transition scale from layer 1 to 2) (transition scale from layer 2 to 3) (...)

Constructor Detail

ScaleFilterLayer

public ScaleFilterLayer()

Initializes an empty layer.

Method Detail

getLayers

public java.util.Vector<Layer> getLayers()

Get the Vector holding the Layers. If it hasn't been asked for yet, a new, empty Vector will be returned, one that will be used internally.

getTransitionScales

public float[] getTransitionScales()

Get the transition scales used to set the active layer.

setLayersAndScales

public void setLayersAndScales(java.util.Vector<Layer> list,
                               float[] scales)

Programmatic way to set layers and scales. There should be one more layer on the list than there is scale in the float array. Layers that should be displayed for larger scale numbers (smaller scale) should be at the front of the Vector list, and larger numbers should be at the front of the scale array. For scale numbers larger than the first number in the array, the first layer will be displayed. As the scale number decreases, other layers will be displayed.

Parameters:

list - Vector of layers

scales - Array of transition scales.

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)

Initializes this layer from the given properties.

Specified by:

prefix - the token to prefix the property names

getProperties

public java.util.Properties getProperties(java.util.Properties props)

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.

getAppropriateLayer

public Layer getAppropriateLayer()

Get the layer that's appropriate at the current scale. The targetedIndex needs to be set before this is called. The targetedIndex is the index to the layers array representing the current layer.

Returns:

Layer

parseLayers

protected void parseLayers(java.lang.String prefix,

updateLayerStatus

public void updateLayerStatus(LayerStatusEvent evt)

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)
