Constructor Detail

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 Detail

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

public Geometry readGeometry()
                      throws NoSuchAuthorityCodeException,
                             FactoryException,
                             XMLStreamException,
                             IOException

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
