Interface FeatureFactory

All Known Implementing Classes:

AbstractFeatureFactoryImpl, AppSchemaFeatureFactoryImpl, LenientFeatureFactoryImpl, ValidatingFeatureFactoryImpl

public interface FeatureFactory

Factory for creation of attributes, associations, and features.

Implementations of this interface should not contain any "special logic" for creating attributes and features. Method implementations should be straight through calls to a constructor.

Since:

2.2

Method Detail

createAssociation

Association createAssociation(Attribute value,
                              AssociationDescriptor descriptor)

Creates an association.

Parameters:

value - The value of the association, an attribute.

descriptor - The association descriptor.

createAttribute

Attribute createAttribute(Object value,
                          AttributeDescriptor descriptor,
                          String id)

Creates an attribute.

Parameters:

value - The value of the attribute, may be null.

descriptor - The attribute descriptor.

id - The id of the attribute, may be null.

createGeometryAttribute

GeometryAttribute createGeometryAttribute(Object geometry,
                                          GeometryDescriptor descriptor,
                                          String id,
                                          CoordinateReferenceSystem crs)

Creates a geometry attribute.

descriptor.getType() must be an instance of GeometryType.

Parameters:

geometry - The value of the attribute, may be null.

descriptor - The attribute descriptor.

id - The id of the attribute, may be null.

crs - The coordinate reference system of the attribute, may be null.

createComplexAttribute

ComplexAttribute createComplexAttribute(Collection<Property> value,

                                        String id)

Creates a complex attribute.

descriptor.getType() must be an instance of ComplexType.

Parameters:

value - The value of the attribute, a collection of properties.

descriptor - The attribute descriptor.

id - The id of the attribute, may be null.

createComplexAttribute

ComplexAttribute createComplexAttribute(Collection<Property> value,
                                        ComplexType type,
