Constructor Detail

LnbCell

public LnbCell(visad.DataReference buoyProfileRef)
        throws visad.VisADException,
               java.rmi.RemoteException

Constructs from data references.

Parameters:

buoyProfileRef - The input buoyancy profile reference.

Throws:

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.

Method Detail

compute

protected visad.Data compute(visad.Data[] datums)
                      throws visad.TypeException,
                             visad.VisADException,
                             java.rmi.RemoteException

Computes the pressure at the Level of Neutral Buoyancy (LNB) of a (AirPressure -> MassicVolume) buoyancy profile.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction: datums[0] is the buoyancy profile.

Returns:

The pressure at the LNB of the buoyancy profile.

Throws:

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

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

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.
