    • XmlStreamGeometryReader

      public XmlStreamGeometryReader(XMLStreamReader reader)
      Create a new instance of the XML Stream Geometry Reader.
      Parameters:
      reader - the reader providing the data to parse
    • XmlStreamGeometryReader

      public XmlStreamGeometryReader(XMLStreamReader reader, GeometryFactory geometryFactory)
      Create a new instance of the XML Stream Geometry Reader.
      Parameters:
      reader - the reader providing the data to parse
      geometryFactory - a specific GeometryFactory to use for constructing geometries
    • XmlStreamGeometryReader

      public XmlStreamGeometryReader(XMLStreamReader reader, GeometryFactory geometryFactory, CurvedGeometryFactory curvedGeometryFactory)
      Create a new instance of the XML Stream Geometry Reader.
      Parameters:
      reader - the reader providing the data to parse
      geometryFactory - a specific GeometryFactory to use for constructing geometries
      curvedGeometryFactory - a specific CurvedGeometryFactory to use for constructing curved geometries
  • Method Details

    • setGeometryFactory

      public void setGeometryFactory(GeometryFactory geometryFactory)
    • getGeometryFactory

      public GeometryFactory getGeometryFactory()
    • isUnsafeXMLAllowed

      public boolean isUnsafeXMLAllowed()
    • setUnsafeXMLAllowed

      public void setUnsafeXMLAllowed(boolean unsafeXMLAllowed)
      Parameters:
      unsafeXMLAllowed - true if you want to parse from an XMLStreamReader not configured for safe XML parsing (XMLInputFactory.SUPPORT_DTD is true)
    • setInvertAxisNeeded

      public void setInvertAxisNeeded(Predicate<CoordinateReferenceSystem> invertAxisNeeded)
      By default axis are not inverted, you can provide a predicate that determines whether axes need to be inverted for a CRS (only called once per CRS).
    • readGeometry

      Reads the next Geometry from the stream.

      Precondition: parser cursor positioned on a geometry property (eg. gml:Point, etc).

      Postcondition: parser gets positioned at the end tag of the element it started parsing the geometry at.

      Throws:
      XMLStreamException - when the parser cursor is not positioned on the expected element
      NoSuchAuthorityCodeException - when parsing the EPSG code fails
      FactoryException - when finding an EPSG parser fails
      IOException - unkown error
