FlatFileDataSource

public FlatFileDataSource()
Parameterless ctor


FlatFileDataSource

public FlatFileDataSource(DataSourceDescriptor descriptor,
                          String filename,
                          Hashtable properties)
                   throws VisADException
Just pass through to the base class the ctor arguments.

Parameters:
descriptor - Describes this data source, has a label etc.
filename - This is the filename (or url) that points to the actual data source.
properties - General properties used in the base class idv * @throws VisADException problem getting the data
Throws:
VisADException
Method Detail

doMakeDataChoices

protected void doMakeDataChoices()
This method is called at initialization time and should create a set of DirectDataChoice-s and add them into the base class managed list of DataChoice-s with the method addDataChoice.

Overrides:
doMakeDataChoices in class DataSourceImpl

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:
The Data object represented by the given dataChoice
Throws:
RemoteException - Java RMI problem
VisADException - VisAD problem
