◆ is_relationally_comparable()

template<typename TableView >
bool cudf::detail::is_relationally_comparable ( TableView const &  lhs,
TableView const &  rhs 

Indicates whether respective columns in input tables are relationally comparable.

lhsThe first table
rhsThe second table (may be the same table as lhs)
true all of respective columns on lhs and 'rhstables are comparable. @return false any of respective columns onlhsand 'rhs tables are not comparable.
