Interface SimpleFeatureFactory


public interface SimpleFeatureFactory

This interface denotes a factory capable of producing SimpleFeature.

This is an abstract factory describing how to create a set of classes targeted towards a SimpleFeature implementation. The methods below define no additional capability over Simp


Method Summary
 Attribute createAttribute(Object value, AttributeDescriptor descriptor, String id)
          Creates a new attribute (always nested).
 GeometryAttribute createGeometryAttribute(Object value, AttributeDescriptor desc, String id, CoordinateReferenceSystem crs)
          Creates a new geometry attribute (always nested).
 SimpleFeature createSimpleFeature(List attributes, SimpleFeatureType type, String id)
          Creates a new simple feature.
 SimpleFeatureCollection createSimpleFeatureCollection(SimpleFeatureCollectionType type, String id)
          Createsa a new simple feature collection.
 

Method Detail

createAttribute

Attribute createAttribute(Object value,
                          AttributeDescriptor descriptor,
                          String id)
Creates a new attribute (always nested).

As currently defined this factory allows for the explicit creation of:

Parameters:
value - The value of the attribute, may be null depending on type.
descriptor - The attribute descriptor.
id - The id of the attribute, may be null depending on type.

createGeometryAttribute

GeometryAttribute createGeometryAttribute(Object value,
                                          AttributeDescriptor desc,
                                          String id,
                                          CoordinateReferenceSystem crs)
Creates a new geometry attribute (always nested).

Parameters:
value - The initial value of the attribute, may be null depending on the type of the type of the attribute.
desc - The attribute descriptor.
id - The id of the attribute, may be null depending on the type.
crs - The coordinate reference system of the attribute, may be null.
Throws:
IllegalArgumentException - If desc.getType() does not return an instanceof GeometryType.

createSimpleFeature

SimpleFeature createSimpleFeature(List attributes,
                                  SimpleFeatureType type,
                                  String id)
Creates a new simple feature.

Parameters:
attributes - attributes order dicated by provided type
type - Type of SimpleFeature to be created
id - The id of the feature, (fid), may be null depending on the type.
Throws:
IllegalArgumentException - If desc.getType() does not return an instanceof SimpleFeatureType.

createSimpleFeatureCollection

SimpleFeatureCollection createSimpleFeatureCollection(SimpleFeatureCollectionType type,
                                                      String id)
Createsa a new simple feature collection.

Parameters:
type - Type of SimpleFeatureCollection to be created
id - The id of the feature collection
Throws:
IllegalArgumentException - If desc.getType() does not return an instanceof SimpleFeatureCollectionType.
