public interface BinaryEvaluatedTC

extends TupleCollection

This interface represent a result of a Medor Query. It is dynamic because the evaluator search result and iterate them by filtering the left and the right tuples.

Method Summary

int	getLeftTCCursor() Get the current row of the left TupleCollection
