                          com.bbn.openmap.layer.shape.ShapeLayer

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

Direct Known Subclasses:
  AreaShapeLayer, BufferedShapeLayer, MultiShapeLayer

public class ShapeLayer
extends OMGraphicHandlerLayer
implements java.awt.event.ActionListener, DataBoundsProvider

An OpenMap Layer that displays shape files. Note that the ESRIRecords have been updated so that the OMGraphics that get created from them are loaded with an Integer object that notes the number of the record as it was read from the .shp file. This lets you align the object with the correct attribute data in the .dbf file.

Constructor Detail

### ShapeLayer

    public ShapeLayer()

  Initializes an empty shape layer.

### ShapeLayer

    public ShapeLayer(java.lang.String shapeFileName)

  This method gets called from setProperties.

  Parameters:
    `realPrefix` - This prefix has already been scoped, which means it is an empty string if setProperties was called with a null prefix, or it's a String ending with a period if it was defined with characters.
    `props` - Properties containing information about files and the layer.

### setProperties

    public void setProperties(java.lang.String prefix,
