Detailed Description

Performs a relational comparison between two elements in two tables.

Constructor & Destructor Documentation

cudf::row::primitive::row_equality_comparator::row_equality_comparator	(	cudf::nullate::DYNAMIC const &	has_nulls,
		std::shared_ptr< cudf::experimental::row::equality::preprocessed_table >	lhs,
		std::shared_ptr< cudf::experimental::row::equality::preprocessed_table >	rhs,
		null_equality	nulls_are_equal
	)

inline

Construct a new row equality comparator object.

Parameters

has_nulls	Indicates if either input column contains nulls
lhs	Preprocessed table containing the first element
rhs	Preprocessed table containing the second element (may be the same as lhs)
nulls_are_equal	Indicates if two null elements are treated as equivalent

bool cudf::row::primitive::row_equality_comparator::operator()	(	size_type	lhs_row_index,
		size_type	rhs_row_index
	)		const

inline

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)
