Interface Tieable

All Superinterfaces:

All Known Implementing Classes:

public interface Tieable

extends java.io.Serializable

A Tieable object has an associated serial number. The value of the serial should increase when the value of the object changes. A Tieable can "sync" with another Tieable, presumably by copying its serial number and other information. A given Tieable might only be able to synchronize with other Tiebles of certain types. If its sync() method is called with an object of the wrong type, it should probably thrown an IllegalArguemntException. See the "Tie" and "Controller" classes for information about how Tieable are used.

Method Summary

long	getSerialNumber() Get the serial number associated with this Tieable.
void	sync(Tie tie, Tieable newest) This routine is called to tell this Tieable that the serial numbers of the Tieables that have been added to the Tie do not match.

Method Detail

getSerialNumber

public long getSerialNumber()

Get the serial number associated with this Tieable. If the value of this Tieable changes, then the serial number should increase.

sync

public void sync(Tie tie,
                 Tieable newest)

This routine is called to tell this Tieable that the serial numbers of the Tieables that have been added to the Tie do not match. newest has a serial number that is at least as large as the serial number of any other Tieable in the Tie. This Tieable should synchronize its value and serial number with the "newest" Tieables. (Note: So far, I haven't found any reason to use the Tie parameter in this method! Maybe it should be removed.)
