template<bool has_nulls = true>
template<typename Element , std::enable_if_t< cudf::is_relationally_comparable< Element, Element >()> * = nullptr>
Performs a relational comparison between the specified elements.
- Parameters
-
| lhs_element_index | The index of the first element |
| rhs_element_index | The index of the second element |
| null_precedence | Indicates how null values are ordered with other values |
- Returns
- weak_ordering Indicates the relationship between the elements in the
lhs and rhs columns.
