Method Detail

parseFeature

public static SimpleFeature parseFeature(ElementInstance instance,
                                         Node node,
                                         Object value,
                                         FeatureTypeCache ftCache,
                                         BindingWalkerFactory bwFactory)
                                  throws Exception

Utility method to implement Binding.parse for a binding which parses into A feature.

Parameters:

instance - The instance being parsed.

node - The parse tree.

value - The value from the last binding in the chain.

ftCache - The feature type cache.

bwFactory - Binding walker factory.

Returns:

A feature type.

Throws:

Exception

featureType

public static SimpleFeatureType featureType(Node node)
                                     throws Exception

Turns a parse node instance into a geotools feature type.

For each child element and attribute of the node a geotools attribute type is created. AttributeType#getName() is derived from the name of the child element / attribute. Attribute#getType() is derived from the class of the value of the child element / attribute.

Attribute types for the mandatory properties of any gml feature type (description,name,boundedBy) are also created.

Parameters:

node - The parse node / tree for the feature.

Returns:

A geotools feature type

Throws:

Exception

featureType

public static SimpleFeatureType featureType(XSDElementDeclaration element,
                                            BindingWalkerFactory bwFactory)
                                     throws Exception

Turns a xml type definition into a geotools feature type.

Parameters:

element - The element declaration.

bwFactory - The binding walker factory.

Returns:

The corresponding geotools feature type.

Throws:

Exception

featureType

public static SimpleFeatureType featureType(XSDElementDeclaration element,
                                            BindingWalkerFactory bwFactory,
                                            CoordinateReferenceSystem crs)
                                     throws Exception

Turns a xml type definition into a geotools feature type.

Parameters:

element - The element declaration.

bwFactory - The binding walker factory.

crs - The coordinate reference system to use on this feature type.

Returns:

The corresponding geotools feature type.

Throws:

Exception

                             throws Exception

Throws:

Exception

crs

public static CoordinateReferenceSystem crs(Node node)

asCollection

public static Collection asCollection(GeometryCollection gc)

Wraps the elements of a geometry collection in a normal collection.
