| Concatenates all strings in the column into one new string delimited by an optional separator string. More... | |
| std::unique_ptr< column > | cudf::strings::concatenate (table_view const &strings_columns, strings_column_view const &separators, string_scalar const &separator_narep=string_scalar("", false), string_scalar const &col_narep=string_scalar("", false), separator_on_nulls separate_nulls=separator_on_nulls::YES, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource()) |
| Concatenates a list of strings columns using separators for each row and returns the result as a strings column. More... | |
