Method Detail

arrayVariableAdapter

public static ArrayVariableAdapter arrayVariableAdapter(dods.dap.DArray array,
                                                        dods.dap.DAS das,
                                                        VariableAdapterFactory factory)
                                                 throws VisADException,
                                                        RemoteException

Returns an instance corresponding to a DODS DArray.

Parameters:

array - The DODS DArray. Only the DODS metadata is used: the array 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.

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.

getFunctionType

public FunctionType getFunctionType()

Returns the VisAD FunctionType of this instance.

Returns:

The FunctionType of this instance.

getRepresentationalSets

public SimpleSet[] getRepresentationalSets(boolean copy)

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

Overrides:

getRepresentationalSets in class VariableAdapter

Parameters:

copy - If true, then the array is copied.

Returns:

The VisAD Sets used to represent the data values in the range of a FlatField.

data

public DataImpl data(dods.dap.DArray array,
                     boolean copy)
              throws VisADException,
                     RemoteException

Returns the VisAD DataImpl corresponding to a DODS DArray.

Overrides:

data in class VariableAdapter

Parameters:

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

copy - If true, then data values are copied.

Returns:

The VisAD data object of this instance. The object will be a FieldImpl and may be a FlatField or FileFlatField.

Throws:

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

RemoteException - Java RMI failure.

setField

public void setField(dods.dap.DArray array,
                     FieldImpl field,
                     boolean copy)
              throws VisADException,
                     RemoteException

Sets a compatible VisAD Field. This method is used by GridVariableAdapter for the DArray portion of a DODS DGrid.

Parameters:

array - The DODS DArray to be used to set a compatible VisAD Field. The array must be compatible with the array used to construct this instance.

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

field - The VisAD Field to be set. The field must be compatible with the array.

Throws:

VisADException

RemoteException
