Compares the underlying iterators. Inverse comparisons are applied in order to take into account that the iterator order is reversed.

Parameters

lhs, rhs

-

iterator adaptors to compare

Return Value

1) lhs.base() == rhs.base()

2) lhs.base() != rhs.base()

3) lhs.base() > rhs.base()

4) lhs.base() >= rhs.base()

5) lhs.base() < rhs.base()

6) lhs.base() <= rhs.base()
