Method Detail

compute

public AtomicValue compute(AtomicValue a,
                  AtomicValue b,
                  XPathContext c)
                    throws XPathException

Description copied from class: Calculator

Perform an arithmetic operation

Specified by:

compute in class Calculator

Parameters:

a - the first operand. Must not be null, and must be an instance of the type implied by the class name.
