Method Detail

compute

protected Data compute(Data[] datums)
                throws TypeException,
                       VisADException,
                       RemoteException

Computes the output water-vapor mixing-ratio from pressure and dew-point temperature.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction: datums[0] is the dew-point temperature and datums[1] is the pressure.

Returns:

The corresponding water-vapor mixing-ratio.

Throws:

ClassCastException - if an input data reference has the wrong type of data object.

TypeException - if a VisAD data object has the wrong type.

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.
