source: tmcsimulator/trunk/src/atmsdriver/model/FEPLine.java @ 184

Revision 184, 2.8 KB checked in by jtorres, 9 years ago (diff)

highways.java: converted to immutable, removed use of FEPLineLoader and added loadLines(), loadLine(), loadStation(), and loadLoop() methods. Renamed loadHighways() to configureHighways(), renamed writeHighwaysMeta() to getHighwaysMeta() which now returns a String containing metadata instead of opening a file and writing to it, which is more flexible. FEPLineLoader.java: deleted, no longer need it. FEPLine.java: converted to immutable, removed unnecessary member variables and adjusted all methods accordingly. Station.java: MLTotVol() and OppTotVol?() are now being updated at end of updateByDirection(). ATMSDriver.java: Now using one config file: highways_fullmap.txt, as opposed to the older lds.txt and loop.txt files. config/vds_data: added highways_fullmap.txt. config/atms_driver_config.properties, atms_driver_config_local.properties: updated config to reflect use of highways_fullmap.txt instead of old loop.txt and lds.txt configuration. ATMSBatchDriver.java: conformed highways initialization in constructor to reflect use of highways_fullmap.txt
