Class McvDataManager

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

public class McvDataManager
extends 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.

Field Summary

getHydraDisplay

public MultiSpectralDisplay getHydraDisplay(DataChoice choice)

loadDataSourceXml

public void loadDataSourceXml(XmlResourceCollection resources)

resources - The XmlResourceCollection that holds the set of datasource xml documents. This may be null.

sortTwoFacedObjects

private ArrayList<TwoFacedObject> sortTwoFacedObjects(ArrayList<TwoFacedObject> objs)
