writeExtendedData

public void writeExtendedData(XMLStreamWriter xmlOut,
                              ResultSet rs)
                       throws XMLStreamException,
                              SQLException

The ExtendedData element offers three techniques for adding custom data to a KML Feature (NetworkLink, Placemark, GroundOverlay, PhotoOverlay, ScreenOverlay, Document, Folder). These techniques are Adding untyped data/value pairs using the Data element (basic) Declaring new typed fields using the Schema element and then instancing them using the <SchemaData> element (advanced) Referring to XML elements defined in other namespaces by referencing the external namespace within the KML file (basic) These techniques can be combined within a single KML file or Feature for different pieces of data. Syntax : <ExtendedData> <Data name="string"> <displayName>...</displayName> <!-- string --> <value>...</value> <!-- string --> </Data> <SchemaData schemaUrl="anyURI"> <SimpleData name=""> ... </SimpleData> <!-- string --> </SchemaData> <namespace_prefix:other>...</namespace_prefix:other> </ExtendedData>

Parameters:

xmlOut -

Throws:

XMLStreamException

SQLException

writeSimpleData

public void writeSimpleData(XMLStreamWriter xmlOut,
                            String columnName,
                            String value)
                     throws XMLStreamException

Parameters:

xmlOut -

Throws:

XMLStreamException
