java.lang.Object
org.geotools.geojson.DelegatingHandler<org.geotools.api.feature.simple.SimpleFeatureType>
org.geotools.geojson.feature.FeatureTypeHandler
All Implemented Interfaces:
org.geotools.geojson.IContentHandler<org.geotools.api.feature.simple.SimpleFeatureType>, org.json.simple.parser.ContentHandler
public class FeatureTypeHandler extends org.geotools.geojson.DelegatingHandler<org.geotools.api.feature.simple.SimpleFeatureType> implements org.geotools.geojson.IContentHandler<org.geotools.api.feature.simple.SimpleFeatureType>

Obtains a complete feature type from GeoJSON by parsing beyond first feature and finding attributes that did not appear in the first feature or had null values.

If null values are encoded, parsing will stop when all data types are found. In the worst case, all features will be parsed. If null values are not encoded, all features will be parsed anyway.
