Constructor Detail

DewPointExtractorCell

public DewPointExtractorCell(DataReference dewProfileRef,
                             DataReference presRef)
                      throws VisADException,
                             RemoteException

Constructs from input data cells.

Parameters:

dewProfileRef - The input dew-point profile reference.

presRef - The input pressure reference.

Throws:

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.

Method Detail

compute

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

Computes the output dew-point.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction. datums[0] is the dew-point profile and datums[1] is the pressure at which to interpolate the dew-point profile.

Returns:

The dew-point of the profile at the given pressure.

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.
