Constructor Detail

LnbCell

public LnbCell(DataReference buoyProfileRef)
        throws VisADException,
               RemoteException

Constructs from data references.

Parameters:

buoyProfileRef - The input buoyancy profile 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 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:

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.
