Detailed Description

Performs a relational comparison between two elements in two tables.

Template Parameters

Nullate A cudf::nullate type describing how to check for nulls

Definition at line 235 of file row_operators.cuh.

Constructor & Destructor Documentation

template<typename Nullate >

cudf::row_equality_comparator< Nullate >::row_equality_comparator	(	Nullate	has_nulls,
		table_device_view	lhs,
		table_device_view	rhs,
		null_equality	nulls_are_equal = `null_equality::EQUAL`
	)

inline

Construct a new row equality comparator object.

Parameters

has_nulls	Indicates if either input column contains nulls
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 245 of file row_operators.cuh.

template<typename Nullate >

bool cudf::row_equality_comparator< Nullate >::operator()	(	size_type	lhs_row_index,
		size_type	rhs_row_index
	)		const

inlinenoexcept

Compares the specified rows for equality.

Parameters

lhs_row_index	The index of the first row to compare (in the lhs table)
rhs_row_index	The index of the second row to compare (in the rhs table)
