template<bool has_nulls = true>
class cudf::element_equality_comparator< has_nulls >
Performs an equality comparison between two elements in two columns.
- Template Parameters
-
| has_nulls | Indicates the potential for null values in either column. |
Definition at line 166 of file row_operators.cuh.
◆ element_equality_comparator()
template<bool has_nulls = true>
Construct type-dispatched function object for comparing equality between two elements.
- Note
lhs and rhs may be the same.
- Parameters
-
| lhs | The column containing the first element |
| rhs | The column containing the second element (may be the same as lhs) |
| nulls_are_equal | Indicates if two null elements are treated as equivalent |
Definition at line 178 of file row_operators.cuh.
◆ operator()()
template<bool has_nulls = true>
template<typename Element , std::enable_if_t< cudf::is_equality_comparable< Element, Element >()> * = nullptr>
Compares the specified elements for equality.
- Parameters
-
| lhs_element_index | The index of the first element |
| rhs_element_index | The index of the second element |
