Method Detail

exec

public Long 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.

Overrides:
exec in class HashFNV
Parameters:
input - the Tuple to be processed.
Returns:
result, of type T.
Throws:
IOException
