Constructor Detail

DrawingDataSource

public DrawingDataSource()

Default bean constructor; does nothing.

DrawingDataSource

public DrawingDataSource(DataSourceDescriptor descriptor,
                         String filename,
                         Hashtable properties)

Create a new DrawingDataSource

Parameters:

descriptor - descriptor for this DataSource

filename - name of the file (or URL)

properties - extra data source properties

Method Detail

canSaveDataToLocalDisk

public boolean canSaveDataToLocalDisk()

Is this data source capable of saving its data to local disk

Specified by:

canSaveDataToLocalDisk in interface DataSource

Overrides:

canSaveDataToLocalDisk in class DataSourceImpl

Returns:

Can save to local disk

initAfterUnpersistence

public void initAfterUnpersistence()

Initialize if being unpersisted.

Specified by:

initAfterUnpersistence in interface DataSource

Overrides:

initAfterUnpersistence in class FilesDataSource

doMakeDataChoices

protected void doMakeDataChoices()

Make the data choices associated with this source

Overrides:

doMakeDataChoices in class DataSourceImpl

getDataInner

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

Actually get the data identified by the given DataChoce. The default is to call the getDataInner that does not take the requestProperties. This allows other, non unidata.data DataSource-s (that follow the old API) to work.

Overrides:

getDataInner in class DataSourceImpl

Parameters:

dataChoice - The data choice that identifies the requested data.

category - The data category of the request.

dataSelection - Identifies any subsetting of the data.

requestProperties - Hashtable that holds any detailed request properties.

Returns:

The visad.Data object

Throws:

RemoteException - Java RMI problem

VisADException - VisAD problem
