All Implemented Interfaces:

gov.nasa.worldwind.avlist.AVList, gov.nasa.worldwind.Disposable, gov.nasa.worldwind.event.MessageListener, gov.nasa.worldwind.layers.Layer, gov.nasa.worldwind.Restorable, gov.nasa.worldwind.WWObject, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener

public class MapLayer
extends gov.nasa.worldwind.layers.AnnotationLayer
implements java.io.Serializable

Annotation layer that can be used to add annotations to the map.
WARNING! NOT ALL FIELDS ARE SERIALIZED!
Only sub-classes of GlobeAnnotations (incl. ToggleAnnotation) will be serialized! All annotations will be converted to ToggleAnnotations during serialization as WWJ-supplied annotations are not Serializable.

public MapLayer()

Method Detail

makeAnnotation

private ToggleAnnotation makeAnnotation(java.lang.String unselectedText,
                              java.lang.String selectedText,
                              gov.nasa.worldwind.geom.Position pos)

Factory to build a toggling annotation.

Parameters:

unselectedText - - text when annotation is not selected

selectedText - - text when annotation is selected

pos - - position of annotation

Returns:

- annotation that can be added to the layer

addToggleAnnotation

public void addToggleAnnotation(java.lang.String unselectedText,
                       java.lang.String selectedText,
                       gov.nasa.worldwind.geom.Position pos)

Convenience method that adds an annotation that is viewable from any altitude. This method is equivalent to directly calling addAnnotation() (inherited from AnnotationLayer) with an instance of ToggleAnnotation.

Parameters:

unselectedText - - text when annotation is not selected

selectedText - - text when annotation is selected

pos - - position of annotation

addToggleAnnotation

public void addToggleAnnotation(java.lang.String unselectedText,
                       java.lang.String selectedText,
                       gov.nasa.worldwind.geom.Position pos,
                       double minAltitude,
                       double maxAltitude)

Convenience method that adds an annotation that is viewable between a min and max altitude. This method is equivalent to directly calling addAnnotation() (inherited from AnnotationLayer) with an instance of ToggleAnnotation where setMinActiveAltitude() and setMaxActiveAltitude() have already been called.

Parameters:

unselectedText - - text when annotation is not selected

selectedText - - text when annotation is selected

pos - - position of annotation

minAltitude - - minimum viewable altitude

maxAltitude - - maximum viewable altitude

writeObject

private void writeObject(java.io.ObjectOutputStream out)
                  throws java.io.IOException

Custom serialization process to serialize non-serializable superclass

Parameters:

out - Output stream for serialization

Throws:

java.io.IOException

readObject

private void readObject(java.io.ObjectInputStream in)
                 throws java.io.IOException,
                        java.lang.ClassNotFoundException

Custom deserialization process to deserialize non-serializable superclass.

Parameters:

in - Input stream for deserialization

Throws:

java.io.IOException

java.lang.ClassNotFoundException

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
