Constructs from references to the indefinite integral, lower limit, upper limit, and a missing-data value.

Parameters:

integralRef - The indefinite integral reference.

lowerRef - The lower limit reference.

upperRef - The upper limit reference.

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 definite integral.

Specified by:

compute in class ComputeCell

Parameters:

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

Returns:

The definite integral value (a Real.

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.
