Class McvDataManager

java.lang.Object
ucar.unidata.data.DataManager
edu.wisc.ssec.mcidasv.data.McvDataManager
public class McvDataManager extends ucar.unidata.data.DataManager

The McvDataManager exists purely as a UI nicety. In the IDV, the list of DataSources are presented in the same ordering found in datasources.xml.

While ordering the contents of datasources.xml certainly would have been easier, the approach taken here is a bit more future-proof. McV simply sorts the data sources known to the IDV.
