public class ListVariableAdapter
extends VariableAdapter

Provides support for adapting a DODS DList variable to the VisAD data-import context.

Instances are immutable.

Method Summary

Method Detail

listVariableAdapter

public static ListVariableAdapter listVariableAdapter(dods.dap.DList list,
                                                      dods.dap.DAS das,
                                                      VariableAdapterFactory factory)
                                               throws VisADException,
                                                      java.rmi.RemoteException

Returns an instance of this class corresponding to a DODS DList.

Parameters:

list - The DODS variable. Only the DODS metadata is used: the variable needn't have any actual data.

das - The DODS DAS in which the attribute table for the DODS variable is embedded.

factory - A factory for creating variable adapters.

Returns:

An instance of this class corresponding to the input arguments.

Throws:

VisADException - VisAD failure.

java.rmi.RemoteException - Java RMI failure.

getMathType

public MathType getMathType()

Returns the VisAD MathType of this instance.

Specified by:

getMathType in class VariableAdapter

Returns:

The MathType of this instance.

getRepresentationalSets

public SimpleSet[] getRepresentationalSets(boolean copy)

Returns the VisAD Sets that will be used to represent this instances data values in the range of a VisAD FlatField.

Overrides:

getRepresentationalSets in class VariableAdapter

Parameters:

copy - If true, then the array is cloned.

Returns:

The VisAD Sets used to represent the data values in the range of a FlatField. WARNING: Modify only under duress.

data

public DataImpl data(dods.dap.DList list,
                     boolean copy)
              throws VisADException,
                     java.rmi.RemoteException

Returns the VisAD DataImpl corresponding to a DODS DList.

Overrides:

data in class VariableAdapter

Parameters:

list - The DODS variable to have the corresponding VisAD data object returned. The variable must be compatible with the variable used to construct this instance.

copy - If true, then the data values are copied.

Returns:

The VisAD data object of this instance. The class of the object will be FileFlatField FlatField, or FieldImpl.

Throws:

VisADException - VisAD failure. Possibly the variable wasn't compatible with the variable used to construct this instance.

java.rmi.RemoteException - Java RMI failure.
