It triggers a calculation based on ComputeCallbacks that are generated by the current states. ........ r2128 | ingo | 2011-06-16 10:25:06 +0200 (Do, 16 Jun 2011) | 1 line Moved Waterlevel state into the correct package. ........ r2129 | ingo | 2011-06-16 10:43:58 +0200 (Do, 16 Jun 2011) | 1 line Added two more compute() methods to ComputeCallback to distinguish between different phases of the artifact. ........ r2130 | ingo | 2011-06-16 10:57:05 +0200 (Do, 16 Jun 2011) | 1 line Use enums to dispatch computeFeed() and computeAdvance(). ........ r2131 | ingo | 2011-06-16 11:04:59 +0200 (Do, 16 Jun 2011) | 1 line Store facets for each state. ........ r2132 | ingo | 2011-06-16 12:05:44 +0200 (Do, 16 Jun 2011) | 1 line Generated facets for each output aspect. ........ r2133 | ingo | 2011-06-16 15:24:00 +0200 (Do, 16 Jun 2011) | 1 line Write computed facets into artifacts describe document. ........ r2136 | ingo | 2011-06-16 16:10:49 +0200 (Do, 16 Jun 2011) | 1 line Add index and description of facets to collections describe document. ........ r2137 | ingo | 2011-06-16 16:31:41 +0200 (Do, 16 Jun 2011) | 1 line OutGenerators doOut() takes a facet object now instead of just its name. ........ r2140 | ingo | 2011-06-17 11:19:43 +0200 (Fr, 17 Jun 2011) | 1 line OutGenerators use now facets to fetch necessary data. ........ r2143 | teichmann | 2011-06-17 12:40:54 +0200 (Fr, 17 Jun 2011) | 1 line Removed ComputeCallback because this was thought too complicated. Fixed issue with facets not be re-generated if same state is entered again. ........ r2144 | teichmann | 2011-06-17 13:08:31 +0200 (Fr, 17 Jun 2011) | 1 line make getGauges() more robust ........ r2146 | teichmann | 2011-06-17 13:23:57 +0200 (Fr, 17 Jun 2011) | 1 line mico opt: inter cmps are faster than str cmps. ........ r2150 | teichmann | 2011-06-17 15:10:20 +0200 (Fr, 17 Jun 2011) | 1 line call computeAdvance() if we want to advance. ........ r2151 | teichmann | 2011-06-17 15:45:50 +0200 (Fr, 17 Jun 2011) | 1 line Base WST/CSV exports on facets. TODO: generate the facets. ........ r2153 | teichmann | 2011-06-17 16:03:29 +0200 (Fr, 17 Jun 2011) | 1 line Add facet to access raw computed data. ........ r2154 | teichmann | 2011-06-17 16:37:09 +0200 (Fr, 17 Jun 2011) | 1 line Generate data facets for the computed states. ........ flys-artifacts/trunk@2156 c6561f87-3c4e-4783-a992-168aeb5c3f6f
