OTExample Observer
Revision as of 07:50, 23 February 2010 by Unnamed Poltroon (Talk)
This is a reusable implementation of the omnipresent design pattern "Observer"
Note, that a well designed program in Object Teams will usually not require an explicit Observer infrastructure. See the Stopwatch example for an example, how a plain callin-binding (OTJLD §4) suffices.
This demo should, however, give a quick understanding to some techniques of Object Teams for all who are familiar with the Observer pattern (the OTDT ships with a simpler version of this pattern).
