### Methods

| Name | Description |
| --- | --- |
|[ get_field_code()](../field/get_field_code/#default) | Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.<br>(Inherited from [Field](../field/)) |
|[ get_field_code(include_child_field_codes)](../field/get_field_code/#bool) | Returns text between field start and field separator (or field end if there is no separator).<br>(Inherited from [Field](../field/)) |
|[ remove()](../field/remove/#default) | Removes the field from the document. Returns a node right after the field. If the field's end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns ``None``.<br>(Inherited from [Field](../field/)) |
|[ unlink()](../field/unlink/#default) | Performs the field unlink.<br>(Inherited from [Field](../field/)) |
|[ update()](../field/update/#default) | Performs the field update. Throws if the field is being updated already.<br>(Inherited from [Field](../field/)) |
|[ update(ignore_merge_format)](../field/update/#bool) | Performs a field update. Throws if the field is being updated already.<br>(Inherited from [Field](../field/)) |

### Examples

Shows how to use the BARCODE field to display U.S. ZIP codes in the form of a barcode.

```python
doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
builder.writeln()
# Below are two ways of using BARCODE fields to display custom values as barcodes.
# 1 -  Store the value that the barcode will display in the PostalAddress property:
field = builder.insert_field(field_type=aw.fields.FieldType.FIELD_BARCODE, update_field=True).as_field_barcode()
# This value needs to be a valid ZIP code.
field.postal_address = '96801'
field.is_us_postal_address = True
field.facing_identification_mark = 'C'
self.assertEqual(' BARCODE  96801 \\u \\f C', field.get_field_code())
builder.insert_break(aw.BreakType.LINE_BREAK)
# 2 -  Reference a bookmark that stores the value that this barcode will display:
field = builder.insert_field(field_type=aw.fields.FieldType.FIELD_BARCODE, update_field=True).as_field_barcode()
field.postal_address = 'BarcodeBookmark'
field.is_bookmark = True
self.assertEqual(' BARCODE  BarcodeBookmark \\b', field.get_field_code())
# The bookmark that the BARCODE field references in its PostalAddress property
# need to contain nothing besides the valid ZIP code.
builder.insert_break(aw.BreakType.PAGE_BREAK)
builder.start_bookmark('BarcodeBookmark')
builder.writeln('968877')
builder.end_bookmark('BarcodeBookmark')
doc.save(file_name=ARTIFACTS_DIR + 'Field.BARCODE.docx')
```
