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.

Returns:

The RealTupleType associated with this class.

Throws:

VisADException - Couldn't perform necessary VisAD operation.

create

public static Data create(Data pressure,
                          Data inSituAirTemperature,
                          Data dewPoint)
                   throws TypeException,
                          UnimplementedException,
                          VisADException,
                          RemoteException

Creates an AirDensity data object from data objects for Pressure, InSituAirTemperature, and DewPoint.

Parameters:

pressure - A Pressure data object.

inSituAirTemperature - An InSituAirTemperature data object.

dewPoint - A DewPoint data object.

Returns:

The AirDensity data object computed from the arguments. The type of the object will be that of the arguments after standard promotion.

Throws:

TypeException - At least one argument has wrong type.

UnimplementedException - Necessary operation not yet implemented.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.

create

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

Creates an AirDensity data object from data objects for Pressure, and temperature

Parameters:

pressure - A Pressure data object.

temperature - A temperature data object. If the in-situ temperature is used, then the returned density will be that for dry air; if the virtual temperature is used, then the returned density will be the actual density.

Returns:

The AirDensity data object computed from the arguments. The type of the object will be that of the arguments after standard promotion.

Throws:

TypeException - At least one argument has wrong type.

UnimplementedException - Necessary operation not yet implemented.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.

create

public static FlatField create(FlatField inputField)
                        throws TypeException,
                               UnimplementedException,
                               VisADException,
                               RemoteException

Creates an AirPressure -> AirDensity field from an Pressure -> (InSituAirTemperature, DewPoint) field.

Parameters:

inputField - An Pressure -> (InSituAirTemperature, DewPoint) field.

Returns:

The (AirPressure -> AirDensity) field corresponding to the input field.

Throws:

TypeException - At least one argument has wrong type.

UnimplementedException - Necessary operation not yet implemented.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.
