All Implemented Interfaces:

ILcdPropertyRetrieverProvider

public class TLcdDataObjectPropertyRetrieverProvider
extends Object
implements ILcdPropertyRetrieverProvider

This implementation of ILcdPropertyRetrieverProvider resolves OGC XPath expressions on ILcdDataObject objects.

It supports data models with and without TLcdXMLSchemaMappingAnnotation. If the annotation is present, the XML schema information is used to implement a correct mapping. Otherwise, the data model of the object is mapped to xml automatically. Each property of each type of such a model is mapped as a local element with a name equal to the name of the property.
