AlgebraicByteArrayMathBase.Final
public AlgebraicByteArrayMathBase.Final()
exec
public Double exec(Tuple input)
throws IOException
- Description copied from class:
EvalFunc
- This callback method must be implemented by all subclasses. This
is the method that will be invoked on every Tuple of a given dataset.
Since the dataset may be divided up in a variety of ways the programmer
should not make assumptions about state that is maintained between
invocations of this method.
- Specified by:
exec
in class EvalFunc<Double>
- Parameters:
input
- the Tuple to be processed.
- Returns:
- result, of type T.
- Throws:
IOException
