Method Detail

addListener

public void addListener(DynamicPropertyListener<T> listener)

Description copied from interface: DynamicProperty

Adds a given listener to the underlying property. The listener will be notified each time the property value changes.

Events are not guaranteed to be received in the same order as the underlying property is set.

The listener will be notified synchronously on the same thread that mutates the underlying property, so don't do any long-running work on the thread that notifies the DynamicPropertyListener.

Specified by:

addListener in interface DynamicProperty<T>

removeListener

public void removeListener(DynamicPropertyListener<T> listener)

Description copied from interface: DynamicProperty

Removes a given listener. After remove the given listener will not receive events when this property is changed.

Specified by:

removeListener in interface DynamicProperty<T>

getCurrentValue

public T getCurrentValue()

Description copied from interface: DynamicProperty

Specified by:

getCurrentValue in interface DynamicProperty<T>

setValue

public void setValue(T value)

Description copied from interface: DynamicProperty
