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:

 
  #######################################
  # Properties for ScaleFilterLayer
  #######################################
  scaledFilterLayer.class=com.bbn.openmap.layer.ScaleFilterLayer
  scaledFilterLayer.prettyName=&ltPretty name used on menu&ge
  # List 2 or more layers, 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 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 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:

setProperties in interface PropertyConsumer

Overrides:

Parameters:

props - the Properties holding settings for this layer

prefix - the token to prefix the property names

getProperties

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

Description copied from class: Layer

PropertyConsumer method, to fill in a Properties object, reflecting the current values of the layer. If the layer has a propertyPrefix set, the property keys should have that prefix plus a separating '.' prepended to each propery key it uses for configuration.

Specified by:

getProperties in interface PropertyConsumer

Overrides:

getProperties in class Layer

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

protected 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,

Renders the scale-appropriate layer on the map.

Overrides:

paint in class javax.swing.JComponent

Parameters:

g - a graphics context

updateLayerStatus

public void updateLayerStatus(LayerStatusEvent evt)

Try to handle receiving LayerStatusEvents from child layers. May not always work, depending on what thread sends/receives this event - usually in the Swing thread, and the GUI can't always be updated as expected.

See Also:

NavMouseMode.modeID, SelectMouseMode.modeID, NullMouseMode.modeID

mousePressed

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:
