All Known Subinterfaces:

BindingModel

All Known Implementing Classes:

ReadOnlyBinding

public interface ReadOnlyBindingModel

This interface provides a single-level, 2-dimensional view of a set of data. It groups all non-update methods and handles read-only events. This interface exists only to provide a logical separation between read-only and non-read-only methods and event handling.
