DbfFieldDefa]Abstract field definition. Child classes must override ``type`` class attribute to provide datatype information of the field definition. For more info about types visit `http://www.clicketyclick.dk/databases/xbase/format/data_types.html` Also child classes must override ``defaultValue`` field to provide default value for the field value. If child class has fixed length ``length`` class attribute must be overridden and set to the valid value. None value means, that field isn't of fixed length. Note: ``name`` field must not be changed after instantiation. )name decimalCountstartend ignoreErrorsNFcCs|jdus Jd|jdusJdt|dkrtd|t|}|jjdurC|dur4td|t|}|dkrBtd|n|j}|durLd}||_ ||_||_ ||_ ||_ ||_ dS) zInitialize instance.NzType code must be overriddenz Default value must be overridden zField name "%s" is too longz[%s] Length isn't specifiedrz&[%s] Length must be a positive integer)typeCode defaultValuelen ValueErrorstrupper __class__lengthintr r rr r )selfr rr r stoprrO/var/www/html/venv/lib/python3.10/site-packages/tablib/packages/dbfpy/fields.py__init__Ms*       zDbfFieldDef.__init__cCst|t|kSNreprrotherrrr__eq__jzDbfFieldDef.__eq__cCst|t|kSrrr!rrr__ne__mr$zDbfFieldDef.__ne__cCst|t|kSrrr!rrr__lt__pr$zDbfFieldDef.__lt__cCs t|jSr)hashr rrrr__hash__ss zDbfFieldDef.__hash__cCsHt|dksJ|d}|t|ddd||d||||dS)azDecode dbf field definition from the string data.
