Classes
struct	cudf::experimental::dispatch_void_if_nested< t >
	A map from cudf::type_id to cudf type that excludes LIST and STRUCT types. More...
struct	cudf::experimental::row::strong_index_iterator< Index, Underlying >
	A counting iterator that uses strongly typed indices bound to tables. More...
struct	cudf::experimental::row::lexicographic::physical_element_comparator
	Computes a weak ordering of two values with special sorting behavior. More...
struct	cudf::experimental::row::lexicographic::sorting_physical_element_comparator
	Relational comparator functor that compares physical values rather than logical elements like lists, strings, or structs. It evaluates NaN as equivalent to other NaNs and greater than all other values. More...
class	cudf::experimental::row::lexicographic::device_row_comparator< has_nested_columns, Nullate, PhysicalElementComparator >
	Computes the lexicographic comparison between 2 rows. More...
class	cudf::experimental::row::lexicographic::device_row_comparator< has_nested_columns, Nullate, PhysicalElementComparator >::element_comparator
	Performs a relational comparison between two elements in two columns. More...
struct	cudf::experimental::row::lexicographic::less_comparator< Comparator >
	Wraps and interprets the result of device_row_comparator, true if the result is weak_ordering::LESS meaning one row is lexicographically less than another row. More...
struct	cudf::experimental::row::lexicographic::less_equivalent_comparator< Comparator >
	Wraps and interprets the result of device_row_comparator, true if the result is weak_ordering::LESS or weak_ordering::EQUIVALENT meaning one row is lexicographically less than or equivalent to another row. More...
struct	cudf::experimental::row::lexicographic::preprocessed_table
	Preprocessed table for use with lexicographical comparison. More...
class	cudf::experimental::row::lexicographic::self_comparator
	An owning object that can be used to lexicographically compare two rows of the same table. More...
class	cudf::experimental::row::lexicographic::two_table_comparator
	An owning object that can be used to lexicographically compare rows of two different tables. More...
struct	cudf::experimental::row::equality::physical_equality_comparator
	Equality comparator functor that compares physical values rather than logical elements like lists, strings, or structs. It evaluates NaN not equal to all other values for IEEE-754 compliance. More...
struct	cudf::experimental::row::equality::nan_equal_physical_equality_comparator
	Equality comparator functor that compares physical values rather than logical elements like lists, strings, or structs. It evaluates NaN as equal to other NaNs. More...
class	cudf::experimental::row::equality::device_row_comparator< has_nested_columns, Nullate, PhysicalEqualityComparator >
	Computes the equality comparison between 2 rows. More...
struct	cudf::experimental::row::equality::preprocessed_table
	Preprocessed table for use with row equality comparison or row hashing. More...
class	cudf::experimental::row::equality::self_comparator
	Comparator for performing equality comparisons between two rows of the same table. More...
class	cudf::experimental::row::equality::two_table_comparator
	An owning object that can be used to equality compare rows of two different tables. More...
class	cudf::experimental::row::hash::element_hasher< hash_function, Nullate >
	Computes the hash value of an element in the given column. More...
class	cudf::experimental::row::hash::device_row_hasher< hash_function, Nullate >
	Computes the hash value of a row in the given table. More...
class	cudf::experimental::row::hash::row_hasher
	Computes the hash value of a row in the given table. More...
