Interface Summary
IObservableValue A value whose changes can be tracked by value change listeners.
IValueChangeListener Listener for changes to observable values.
IValueChangingListener Listener for pre-change events for observable values.
IVetoableValue An observable value whose changes can be vetoed by listeners.
 

Class Summary
AbstractObservableValue This class is thread safe.
AbstractVetoableValue This class is thread safe.
ComputedValue A Lazily calculated value that automatically computes and registers listeners on its dependencies as long as all of its dependencies are IObservable objects.
DateAndTimeObservableValue An IObservableValue < Date > which supports scenarios where the date and time are presented as separate elements in the user interface.
DecoratingObservableValue An observable value which decorates another observable value.
DecoratingVetoableValue An IVetoableValue decorator for an observable value.
DuplexingObservableValue  
SelectObservableValue An observable value which behaves similarly to the <select> and <option> HTML tags.
ValueChangeEvent Value change event describing a change of an IObservableValue object's current value.
ValueChangingEvent Value changing event describing a pending change of an IObservableValue object's current value.
ValueDiff  
WritableValue Mutable (writable) implementation of IObservableValue that will maintain a value and fire change events when the value changes.
