public interface GroupAssertionCall<C> extends OperationCall<C>
GroupAssertion
invocation arguments.
This interface is generic, allowing the user to set a custom 'context' object when GroupAssertion.start(cascading.flow.FlowProcess, GroupAssertionCall)
is called. The OperationCall.setContext(Object)
and OperationCall.getContext()
methods are
inherited from OperationCall
.GroupAssertion
,

getArgumentFields, getContext, setContext

.TupleEntry getArguments()
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()
