Package org.zkoss.bind.sys.tracker

Interface Tracker

  • All Known Implementing Classes:
    TrackerImpl, TrackerImplEx
    public interface Tracker
    Bind tracker to maintain a binding dependency graph. e.g. @{a.b.c, save-onchange:d.e.f} then it forms a dependency from d.e.f to a.b.c for save.
