public class AnnotationLayer
The AnnotationLayer class manages a collection of Annotation objects
for rendering and picking. AnnotationLayer delegates to its internal
AnnotationRenderer for rendering and picking operations. The
AnnotationRenderer is specified by calling setAnnotationRenderer(gov.nasa.worldwind.render.AnnotationRenderer).

public void addAnnotation(Annotation annotation)
annotation to this layer's internal collection.
If this layer's internal collection has been overriden with a call to setAnnotations(java.lang.Iterable) ,
this will throw an exception.
annotation - Annotation to add.
IllegalArgumentException - If annotation is null.
IllegalStateException - If a custom Iterable has been specified by a call to setAnnotations.public void addAnnotations(Iterable<Annotation> annotations)
annotations to this layer's internal collection.
If this layer's internal collection has been overriden with a call to setAnnotations(java.lang.Iterable) ,
this will throw an exception.

IllegalArgumentException - If annotations is null.
IllegalStateException - If a custom Iterable has been specified by a call to setAnnotations.

AnnotationRenderer used to pick and render Annotations.public Iterable<Annotation> getAnnotations()
setAnnotations(java.lang.Iterable) , this will returns a reference
to that Iterable. If the caller passed setAnnotations a null parameter,
or if setAnnotations has not been called, this returns a view of this layer's internal
collection of Annotations.
public void removeAllAnnotations()
setAnnotations(java.lang.Iterable) ,
this will throw an exception.
IllegalStateException - If a custom Iterable has been specified by a call to setAnnotations.public void removeAnnotation(Annotation annotation)
annotation from this layer's internal collection, if it exists.
If this layer's internal collection has been overriden with a call to setAnnotations(java.lang.Iterable) ,
this will throw an exception.
annotation - Annotation to remove.
IllegalArgumentException - If annotation is null.
IllegalStateException - If a custom Iterable has been specified by a call to setAnnotations.public void setAnnotationRenderer(AnnotationRenderer annotationRenderer)
AnnotationRenderer this layer delegates to during picking and rendering.
annotationRenderer - AnnotationRenderer used to pick and render Annotations.
IllegalArgumentException - If annotationRenderer is null.public void setAnnotations(Iterable<Annotation> annotationIterable)
annotationIterable.
This layer will maintain a reference to annotationIterable strictly for picking and rendering.
This layer will not modify the Iterable reference. However, this will clear
the internal collection of Annotations, and will prevent any modification to its contents via
addAnnotation, addAnnotations, or removeAnnotations.
If the specified annotationIterable is null, this layer will revert to maintaining its internal
collection.
annotationIterable - Iterable to use instead of this layer's internal collection, or null to use this
layer's internal collection.public String toString()
