exportAttributesAsKML

public static void exportAttributesAsKML(XMLStreamWriter xmlWriter,
                                         String styleType,
                                         ShapeAttributes attributes)
                                  throws XMLStreamException,
                                         IOException

Export ShapeAttributes as KML Pair element in a StyleMap. This method assumes that the StyleMap tag has already been written; it writes the Pair tag.

Parameters:

xmlWriter - Writer to receive the Style element.

styleType - The type of style: normal or highlight. Value should match either KMLConstants.NORMAL or KMLConstants.HIGHLIGHT

attributes - Attributes to export. The method takes no action if this parameter is null.

Throws:

XMLStreamException - if exception occurs writing XML.

IOException - if exception occurs exporting data.

exportBoundaryAsLinearRing

public static void exportBoundaryAsLinearRing(XMLStreamWriter xmlWriter,
                                              Iterable<? extends LatLon> boundary,
                                              Double altitude)
                                       throws XMLStreamException

Export the boundary of a polygon as a KML LinearRing.

Parameters:

xmlWriter - Writer to receive generated XML.

boundary - Boundary to export.

altitude - Altitude of the points in the ring.

Throws:

XMLStreamException - if exception occurs writing XML.

exportDimension

public static void exportDimension(XMLStreamWriter xmlWriter,
                                   Size dimension,
                                   String tagName)
                            throws XMLStreamException

Export a Size as a KML element.

Parameters:

xmlWriter - Writer to receive the Style element.

dimension - The dimension to export. If dimension is null, nothing is written to the stream.

tagName - The name of the KML tag to create.

Throws:

XMLStreamException - if exception occurs writing XML.

exportOffset

public static void exportOffset(XMLStreamWriter xmlWriter,
                                Offset offset,
                                String tagName)
                         throws XMLStreamException

Export an Offset as a KML element.

Parameters:

xmlWriter - Writer to receive the Style element.

offset - The offset to export. If offset is null, nothing is written to the stream.

tagName - The name of the KML tag to create.

Throws:

XMLStreamException - if exception occurs writing XML.

kmlAltitudeMode

public static String kmlAltitudeMode(int altitudeMode)

Convert a WorldWind altitude mode to a KML altitude mode.

Parameters:

altitudeMode - Altitude mode to convert.

Returns:

The KML altitude mode that corresponds to altitudeMode.

Throws:

IllegalArgumentException - If altitudeMode is not a valid WorldWind altitude mode.

kmlBoolean

public static String kmlBoolean(boolean value)

Convert a boolean to binary string "1" or "0".

Parameters:

value - Value to convert.

Returns:

"1" if value is true, otherwise "0".

stripHexPrefix

public static String stripHexPrefix(String hexString)

Strip the "0X" prefix from a hex string.

Parameters:

hexString - String to manipulate.

Returns:

The portion of hexString after the 0X. For example: "0X00FF00" => "00FF00". If the string does not begin with 0X, hexString is returned. The comparison is not case sensitive.
