Constructor & Destructor Documentation

row_equality_comparator()

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

Member Function Documentation

operator()() [1/2]

bool cudf::row::primitive::row_equality_comparator::operator() ( cudf::experimental::row::lhs_index_type  lhs_index, cudf::experimental::row::rhs_index_type  rhs_index  ) const

inline

Compares the specified rows for equality.

Parameters

lhs_index	The index of the first row to compare (in the lhs table)
rhs_index	The index of the second row to compare (in the rhs table)

Returns

Boolean indicating if both rows are equal

operator()() [2/2]

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)

Returns

true if both rows are equal, otherwise false
