- 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.
setAcceptableValues
void setAcceptableValues(java.util.Collection<T> values)
- Set the acceptable values.
- Parameters:
values - the acceptible values
