Method Detail

createDataConfig

public static DataConfiguration createDataConfig(Element domElement)

Creates a standard layer or elevation model configuration backed by a specified "data descriptor" document.

Parameters:: domElement - backing DOM document.
Returns:: Layer or ElevationModel document, or null if the "data descriptor" document cannot be transformed to a standard document.
Throws:: IllegalArgumentException - if the document is null.

getDataDescriptorLatLon

protected static LatLon getDataDescriptorLatLon(Element context,
                                                String path,
                                                XPath xpath)

getDataDescriptorSector

protected static Sector getDataDescriptorSector(Element context,
                                                String path,
                                                XPath xpath)

isInstalledDataDocument

public static boolean isInstalledDataDocument(Element domElement)

Returns true if a specified DOM document should be accepted as a"data descriptor" configuration document, and false otherwise.

Parameters:: domElement - the DOM document in question.
Returns:: true if the document is a "data descriptor" configuration document; false otherwise.
Throws:: IllegalArgumentException - if document is null.

transformCommonElements

transformElevationModelElements

protected static void transformElevationModelElements(Element context,
                                                      Element outElem,
                                                      XPath xpath)

transformInstalledDataDocument

public static Document transformInstalledDataDocument(Element domElement)

Transforms a "data descriptor" document to a standard layer or elevation model configuration document, depending on the contents of the Element.

Parameters:: domElement - DataDescriptor document to transform.
Returns:: standard Layer or ElevationModel dsocument, or null if the DataDescriptor cannot be transformed to a standard document.
Throws:: IllegalArgumentException - if the document is null.

transformLayerElements

protected static void transformLayerElements(Element context,
                                             Element outElem,
