Constructor Detail

VirtualTemperature

protected VirtualTemperature(String name)
                      throws VisADException

Constructs from a name.

Parameters:

name - The name for this quantity.

Throws:

VisADException - Couldn't create necessary VisAD object.

Method Detail

getRealType

public static RealType getRealType()
                            throws VisADException

Obtains the RealType associated with this class.

Returns:

The RealType associated with this class.

Throws:

VisADException - Couldn't perform necessary VisAD operation.

getRealTupleType

public static RealTupleType getRealTupleType()
                                      throws VisADException

Obtains the RealTupleType associated with this class.

createFromDewPoint

public static Data createFromDewPoint(Data pressure,
                                      Data temperature,
                                      Data dewPoint)
                               throws TypeException,
                                      UnimplementedException,
                                      VisADException,
                                      RemoteException

Creates a virtual temperature data object from data objects of air pressure, in situ air temperature, and dew point.

Parameters:

pressure - The air pressure data object.

temperature - The in situ air temperature data object.

dewPoint - The dew point data object.

Returns:

The virtual air temperature corresponding to the arguments. The type of the returned object will be that of the arguments after standard promotion.

Throws:

TypeException - At least one argument has the wrong type.

UnimplementedException - Necessary operation not yet implemented.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.
