setValue
public void setValue(Object value)
Sets the current value of the model to that specified.
Implementations can choose to refuse to accept the value
and throw an exception instead. For example, a date model
may throw invalid dates, or a list model may throw out
values which don't exist in the underlying list. Models
may also throw out unusual values, such as null. The decision
is left to the discretion of the implementator. If the
operation succeeds, the implementation should also notify
any registered ChangeListener
s.
