Constructor Detail

LayerMeanCell

public LayerMeanCell(visad.DataReference proRef,
                     visad.DataReference lowerRef,
                     visad.DataReference upperRef,
                     visad.Real noData)
              throws visad.VisADException,
                     java.rmi.RemoteException

Constructs from a reference to the atmospheric profile, references to the lower and upper limits of the layer, and a missing-data value.

Parameters:

proRef - The atmospheric profile reference.

lowerRef - The lower layer limit.

upperRef - The upper layer limit.

noData - The missing data value.

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 layer mean value.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data. datums[0] is the profile; datums[1] is the lower layer limit; and datums[2] is the upper layer limit.

Returns:

The mean value of the profile parameter.

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.

getMeanPresRef

public visad.DataReference getMeanPresRef()

Returns the mean pressure within the just-computed layer.

Returns:

The mean pressure of the just-computed layer.
