Method Detail

exec

public Tuple 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<Tuple>

Parameters:

input - the Tuple to be processed.

Returns:

result, of type T.

Throws:

IOException
