                           RemoteException

Constructs from a data reference for the function, a data reference for the Set domain, and a missing data value.

Parameters:

funcRef - The function reference.

domainRef - The evaluation domain reference.

noData - The missing data value.

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 value by evaluating the function at the domain points.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data. datums[0] is the function to evaluate and datums[1] is the Set domain at which to evaluate the function.

Returns:

The function at the domain points. The Object has type Field.

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.
