Interface ILcdPropertyRetrieverProvider

All Known Implementing Classes:
TLcdCSWAPISOPropertyRetrieverProvider, TLcdCSWRecordPropertyRetrieverProvider, TLcdDataObjectPropertyRetrieverProvider, TLcdFeaturedDescriptorPropertyRetrieverProvider, TLcdFeaturedDescriptorProviderPropertyRetrieverProvider, TLcdSelfPropertyRetrieverProvider, TLcdXMLElementPropertyRetrieverProvider
public interface ILcdPropertyRetrieverProvider

This interface allows to abstract the way an OGC XPath expression can reference a property of a given object. Implementations of this interface must be thread safe. The created ILcdPropertyRetriever instances however can be non thread safe.

For most use-cases, there is no need to implement this interface yourself. Instead, use the createDefaultPropertyRetrieverProvider(ILcdModel) method to create a ILcdPropertyRetrieverProvider instance.
