  • Method Details

    • getFeatureProperties

      List getFeatureProperties(SimpleFeature f, XSDElementDeclaration element, Encoder e)
      Lists all properties that should be encoded for a given feature
      Parameters:
      f - A sample feature
      element - The xml element holding the feature type
      e - The encoder

    • createEnvelopeEncoder

      ObjectEncoder createEnvelopeEncoder(Encoder e)
      Creates the envelope encoder

    • registerGeometryEncoders

      void registerGeometryEncoders(Map<Class,GeometryEncoder<? extends Geometry>> encoders, Encoder encoder)
      Registers all the geometry encoders for this GML version in a map, by geometry class (different versions support different types of geometries, e.g., GML3 supports also curved ones)

    • setSrsNameAttribute

      void setSrsNameAttribute(AttributesImpl atts, CoordinateReferenceSystem crs)
      Sets the SRS attribute with the proper syntax for the given GML version

    • setGeometryDimensionAttribute

      void setGeometryDimensionAttribute(AttributesImpl srsatts, int dimension)
      Sets the dimensions attribute, if available for the current GML version

    • initFidAttribute

      void initFidAttribute(AttributesImpl atts)
      Initializes an empty feature id attribute, the attribute must be the first one in "atts"

    • endFeatures

      void endFeatures(GMLWriter handler) throws Exception
      Closes a collection of features
      Throws:

      Throws:
      Exception

    • getGmlPrefix

      String getGmlPrefix() throws Exception
      The GML prefix used by this encoding session
      Throws:
      Exception

    • supportsTuples

      boolean supportsTuples()

    • getNumDecimals

      int getNumDecimals()
      Number of decimals used in the output

    • forceDecimalEncoding

      boolean forceDecimalEncoding()
      Returns true if coordinates should be encoded as xs:decimal instead of xs:double

    • padWithZeros

      boolean padWithZeros()
      Returns true if coordinates should be right-padded with zeros up to the requested number of decimals.

    • getEncodeMeasures

      default boolean getEncodeMeasures()
      Controls if coordinates measures should be included in WFS outputs.
      Returns:
      TRUE if measures should be encoded, otherwise FALSE
