      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
    • feature

      public static SimpleFeature feature(SimpleFeatureType fType, String fid, Node node) throws Exception
      Throws:
      Exception
    • crs

      public static CoordinateReferenceSystem crs(Node node)
    • asCollection

      public static Collection<Geometry> asCollection(GeometryCollection gc)
      Wraps the elements of a geometry collection in a normal collection.
