Interface BindingTarget

public interface BindingTarget

BindingTarget allows the target of a binding operation to control the binding.

A bound Binding checks the target if it implements BindingTargetProvider. If the target implements BindingTargetProvider, then createBindingTarget is invoked on it supplying a BindingController.

BindingTarget is primarily useful for targets that need to customize how the binding works, such as a JTable binding.
