Package org.eclipse.core.databinding.observable.value

Provides classes that can be used to observe changes in discrete values.

Package Specification

This package provides classes that can be used to observe changes in discrete values.

Interface Summary

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

Class Summary

Class	Description
AbstractObservableValue<T>	This class is thread safe.
AbstractVetoableValue<T>	This class is thread safe.
ComputedValue<T>	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<T>	An observable value which decorates another observable value.
DecoratingVetoableValue<T>	An IVetoableValue decorator for an observable value.
DuplexingObservableValue<T>	A class to reduce an observable list to a single value in an implementation specific way.
LocalDateTimeObservableValue	An IObservableValue<LocalDateTime> which supports scenarios where the date and time are presented as separate elements in the user interface.
SelectObservableValue<T>	An observable value which behaves similarly to the <select> and <option> HTML tags.
ValueChangeEvent<T>	Value change event describing a change of an IObservableValue object's current value.
ValueChangingEvent<T>	Value changing event describing a pending change of an IObservableValue object's current value.
ValueDiff<T>
WritableValue<T>	Mutable (writable) implementation of IObservableValue that will maintain a value and fire change events when the value changes.
