    • getDelegate

      protected final ISetProperty<S,E> getDelegate(S source)

      Parameters:
      source - the property source (may be null)
      Returns:
      the property to delegate to for the specified source object.

    • doGetDelegate

      protected abstract ISetProperty<S,E> doGetDelegate(S source)
      Returns the property to delegate to for the specified source object. Implementers must ensure that repeated calls to this method with the same source object returns the same delegate instance.
      Parameters:
      source - the property source
      Returns:
      the property to delegate to for the specified source object.
