Interface ILcdPropertyRetriever

All Known Implementing Classes:

TLcdSelfPropertyRetriever

public interface ILcdPropertyRetriever

This interface allows to abstract the way a property is obtained from a given object.

For most use-cases, there is no need to implement this interface yourself. Instead, use the ILcdPropertyRetrieverProvider.createDefaultPropertyRetrieverProvider(ILcdModel) method to create a ILcdPropertyRetrieverProvider instance. This provider can be used to create an instance of this interface.
