Class AnnotationFeatureType

java.lang.Object
  org.geotools.feature.type.AnnotationFeatureType

public class AnnotationFeatureType

extends java.lang.Object

Defines required attributes for Annotations.

Annotations represent a text based geographic feature. The geometry stored in the feature indicates where the text should be drawn and the attribute indicated by the ANNOTATION_ATTRIBUTE_NAME attribute holds the text to be displayed for the feature.

Example:

   if ( feature.getFeatureType().isDescendedFrom( AnnotationFeatureType.ANNOTATION ) )
   {
     String attributeName = (String)feature.getAttribute( AnnotationFeatureType.ANNOTATION_ATTRIBUTE_NAME );
     String annotationText = (String)feature.getAttribute( attributeName );
     ... // Do something with the annotation text and feature
   }
