getDataInner

protected Data getDataInner(DataChoice dataChoice,
 DataCategory category,
 DataSelection dataSelection,
 Hashtable requestProperties)
                     throws VisADException,
RemoteException

This method should create and return the visad.Data that is identified by the given DataChoice.

Overrides:

getDataInner in class DataSourceImpl

Parameters:

dataChoice - This is one of the DataChoice-s that was created in the doMakeDataChoices call above.

category - The specific DataCategory which the DisplayControl was instantiated with. Usually can be ignored.

dataSelection - This may contain a list of times which subsets the request.

requestProperties - extra request properties

Returns:

Data object represented by the given dataChoice

Throws:

RemoteException - Java RMI problem.

VisADException - VisAD problem.
