Just a short update about my commit yesterday, collecting all my changes since the last release. All stuff is pretty rough so far. 1) Map Correction Activating map correction (Administrator => allows to up- and downgrade any hex of the map free of any restriction (except that the tile must exist in the potential upgrade path of the initial tile of the hex). Tokens are not handled so far (especially for those cases where tokens have to be relaid). Implementation is analog to cash corrections: MapCorrectionManager creates and executes MapCorrectionActions. The intermediate steps of tile laying are handled by the Manager class as well (different to the LayTileAction, where the intermediate steps are controlled by the UI classes). 2) Network Info As a preliminary step to route connectivity and route calculation the map and tile information is used to built a network graph. A visualization can be displayed in the MapPanel under Info => NetworkInfo for the complete map or the routes available for each company. Based on the JGraphT library for the datastructure and JGraph for the visual part. It might be necessary to add those to the Eclipse classpath manually, if building through Eclipse. The ant build script is adapted. Implementation: NetworkEdges and -Vertexes are the buidling blocks. NetworkIterator implements the rules for a DFS iterator for the specific rules to traverse an 18xx map. NetworkGraphBuilder contains methods to generate and visualize the graph. 3) Export Allows to export the map as CSV-File with HexID, TileID and Orientation. Stefan |

Stefan, This all sounds really good, I went to have a test this morning and the project properties has a reliance on junit.jar located in c:\java\eclipse521 so it doesn't build straight off the CVS version at the moment. I can fix this locally to test obviously but I think the checked in version needs to be able to run standalone...

Phil: I tried to indicate those issues with Eclipse build in my e-mail, but maybe it was not prominent enough. I have some guilt here as I proposed not to include a JUnit jar into the Rails CVS, as it is a common library under a eclipse and can be activated by a few clicks. But especially as the .classpath file is also part of the CVS this causes those issues. With that current setup it seems to be better to include JUnit somewhere in the CVS. I do not know if lib is a good place, if we do that we have to exclude that from getting into the Rails built. Maybe Brett has a good suggestion where to put it (Maybe create test/lib?). Most likely this will happen soon after we move to a new VCS ;-) Stefan -----Ursprüngliche Nachricht----- Von: Phil Davies <de...@gm...> Gesendet: Apr 6, 2010 11:17:08 AM An: "Development list for Rails: an 18xx game" <rai...@li...> Betreff: Re: [Rails-devel] Map Correction, Network Info, Export Also, the JGraph and JGraphT jar files weren't in the library settings for the project...this might actually just be me being a little stupid with eclipse :p.

The Junit jars can go into /lib. I don't think we need to segregate it. Though, the build.xml should probably be updated to exlude it from the final release package. ---Brett.

Yes, I think all libraries should be put there. I am now having the same problem again with the JGraph jars: Eclipse insists that I have locally changed .classpath (which I have) and keeps insisting that I have to commit that change (which might be OK because these jars are already under /lib).

Stefan,
When trying Network Info, I'm getting an exception:
java.lang.UnsupportedClassVersionError: Bad version number in .class
file
on line 589 in ORPanel.executeNetworkInfo():
NetworkGraphBuilder nwGraph = new NetworkGraphBuilder();
Could this be another Java 5/6 clash?
Another glitch: in NetworkGraphBuilder.iterator, Eclipse consider the
@Override annotation to be an error.
I had to remove it to make this class compile. Could you check if that
annotation can and should be removed indeed?
Erik.

Erik: after my return from Stockholm to my desktop pc I had time to to figure that out: I have now a dual installation of Java 5 and Java 6 on my desktop (not possible for my laptop unfortunately due to hd constraints), that I can test under JRE 5. Stefan Some comments as those might be helpful for similar occasions: > When trying Network Info, I'm getting an exception: > java.lang.UnsupportedClassVersionError: Bad version number in .class > file > on line 589 in ORPanel.executeNetworkInfo(): > NetworkGraphBuilder nwGraph = new NetworkGraphBuilder(); > Could this be another Java 5/6 clash? That occurs if a jar was produced with a newer JDK version than the running JRE, independent of used language features. Thus I had a Java 5 compatible jar of jgraph, which was unfortunately compiled with a JDK version 6. A similar issue arises now with the JUnit jar, which I added to the repository. As it is 3.8.2 it is definitely compatible with Java 5, but as my Eclipse installation was compiled with JDK 6, it seems that this version only runs under JRE 6, but at least it should avoid raising errors at compile time. As I assume that you have a Eclipse installation of Java 5 you could replace the jar in CVS with yours, than the testcases should also run under Java 5. > Another glitch: in NetworkGraphBuilder.iterator, Eclipse consider the > @Override annotation to be an error. > I had to remove it to make this class compile. Could you check if that > annotation can and should be removed indeed? That is (again) the difference in override-annotations between 5 and 6 and I forgot to set the Java 5 compatibility flag on my laptop. |

Even if you have JDK 1.6 installed, you can configure Eclipse to use it as 1.5, which will produce class files compatible with 1.5 and give @Override warnings in the right places for 1.5.

John, thanks for pointing this out. That is actually the setting I use on my desktop (except that I forgot to set it on my laptop). However with out JRE 1.5 I will not find potential problems, if I use JRE 1.6 for running. And at least to my knowledge there is no setting to let the JRE behave like a previous version, or is there? The other issue was that I am to lazy to checkout the sources of JUnit myself and compiling it to to 5 again, if Erik can easily add one which works under Java 5.

But still the bytecode of 1.6 is not compatible with 1.5 (unless the compatibility flag is set - at least I hope that it is then).

No I am not (have not checked that - lazy), but at least the version of the junit jar that comes along with my eclipse build on my suse linux did not work with JRE 5, even if its manifest claims to be built with 1.4. |
