This is a simple structure, which contains ``name``, ``type``, ``len``, ``dec`` and ``cls`` fields. Objects also implement get/setitem magic functions, so fields could be accessed via sequence interface, where 'name' has index 0, 'type' index 1, 'len' index 2, 'dec' index 3 and 'cls' could be located at index 4. )nametypelendecclsNr)CNLDTcCsL|j|\}}|dur|durtd|}||_||_||_||_||_dS)NzField length must be defined) FLD_TYPES ValueErrorrrrrr)selfrrrr_cls_lenr!O/var/www/html/venv/lib/python3.10/site-packages/tablib/packages/dbfpy/dbfnew.py__init__Fs z_FieldDefinition.__init__cCs||j|j|jS)z:Return `DbfFieldDef` instance from the current definition.)rrrrrr!r!r" getDbfFieldRsz_FieldDefinition.getDbfFieldcCs|}||dS)zCreate a `DbfFieldDef` instance and append it to the dbf header.
