# LocalizedBarcodesUnit Class

The `LocalizedBarcodesUnit` class represents a unit that contains localized barcodes unit. It inherits from the `IntermediateResultUnit` class.

## Definition

*Module:* dbr

*Inheritance:* [IntermediateResultUnit]({{ site.dcvb_python_api }}core/intermediate-results/intermediate-result-unit.html) -> LocalizedBarcodesUnit

```python
class LocalizedBarcodesUnit(IntermediateResultUnit)
```

## Methods

| Method                            | Description |
|-----------------------------------|-------------|
| [`add_localized_barcode`](#add_localized_barcode)           | Adds a localized barcode.|
| [`get_localized_barcode`](#get_localized_barcode)           | Gets a localized barcode element.|
| [`get_count`](#get_count)           | Gets the number of localized barcodes in the unit.|
| [`remove_all_localized_barcodes`](#remove_all_localized_barcodes)           | Removes all the localized barcodes.|
| [`remove_localized_barcode`](#remove_localized_barcode)           | Removes a localized barcode at the specified index.|
| [`set_localized_barcode`](#set_localized_barcode)           | Sets a localized barcode at the specified index.|
