Functions

std::unique_ptr< column > cudf::replace_nulls (column_view const &input, column_view const &replacement, rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
 Replaces all null values in a column with corresponding values of another column. More...
 
std::unique_ptr< column > cudf::replace_nulls (column_view const &input, scalar const &replacement, rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
 Replaces all null values in a column with a scalar. More...
 
std::unique_ptr< column > cudf::replace_nulls (column_view const &input, replace_policy const &replace_policy, rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
 Replaces all null values in a column with the first non-null value that precedes/follows. More...
 
std::unique_ptr< column > cudf::replace_nans (column_view const &input, column_view const &replacement, rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
