Method Detail

getArguments

TupleEntry getArguments()
Returns TupleEntry of argument values.

Note that the returned TupleEntry should not be cached (stored in a Collection), nor should the underlying Tuple instance. Where possible Cascading will re-use both TupleEntry and Tuple instances.

To get a safe copy that can be cached, use TupleEntry.getTupleCopy().

Returns:
TupleEntry
