| 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::device_async_resource_ref mr=cudf::get_current_device_resource_ref()) |
| Concatenates a list of strings columns using separators for each row and returns the result as a strings column. More... | |
| std::unique_ptr< column > | cudf::strings::concatenate (table_view const &strings_columns, string_scalar const &separator=string_scalar(""), string_scalar const &narep=string_scalar("", false), separator_on_nulls separate_nulls=separator_on_nulls::YES, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref()) |
| Row-wise concatenates the given list of strings columns and returns a single strings column result. More... | |

| Given a lists column of strings (each row is a list of strings), concatenates the strings within each row and returns a single strings column result. More... | |
