Interface javax.infobus.DataItemChangeListener

public interface DataItemChangeListener
Recipients of data items may optionally implement DataItemChangeListener so that they can register with a data item's optional DateItemChangeManager interface. A data item that implements DataItemChangeManager sends change notifications as DataItemChangeEvents its data changes. Listeners register via the DataItemChangeManager's addDataItemChangeListener method.
