- A new interface called ITemporal (could not at the moment come up with at better name
). The idea is that if time is relevant for an exchange item (input or output) then such exchange items may implement this interface in addition to IInputExchangeItem or IOutputExchangeItem. The TimeHorizon property is moved from the ILinkableComponet to the ITemporal interface, so a time horizon relates to at specific exchange item rather than the whole linkable component.
The property exchangeTime should be regarded exactly as IElementSet. So, the elemetSet defines the locations for where data can be provided or accepted and likewise does the exchangeTime define when data is available or expected. This also means that the GetValues method in the IBridge interface does not need at time argumet. The bridge will convert data from being represented on the output elementset and the output exchange time to be presented on the input elementset at the input exchange time. The AlwaysForwardInTime property is used to tell the other component that the exchange time will never be moved backwards thus allowing the delivering component to clear it's buffer.
