HasConstrainedValue (GWT Javadoc)

Type Parameters:

T - the type of value

All Superinterfaces:

HasHandlers, HasValue<T>, HasValueChangeHandlers<T>, TakesValue<T>

All Known Implementing Classes:

ValueListBox, ValuePicker
```
public interface HasConstrainedValue<T>
extends HasValue<T>
```
Implemented by widgets that pick from a set of values.
It is up to the implementation to decide (and document) how to behave when HasValue.setValue(Object) is called with a value that is not in the acceptable set. For example, throwing an IllegalArgumentException, or quietly adding the value to the acceptable set, are both reasonable choices.
