DbfFieldDefa\Abstract field definition. Child classes must override ``type`` class attribute to provide datatype infromation 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 overriden 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. namelength decimalCountstartend ignoreErrorsNFcCs$|jdk std|jdk s6tdt|dkr[td|nt|j}|jjdkr|dkrtd|nt |}|dkrtd|qn |j}|dkrd}n||_ ||_||_ ||_ ||_ ||_dS) zInitialize instance.NzType code must be overridenzDefault value must be overriden zField name "%s" is too longz[%s] Length isn't specifiedrz&[%s] Length must be a positive integer)typeCodeAssertionError defaultValuelen ValueErrorstrupper __class__r intr r rr r )selfr r r r stoprrQ/var/www/dbchiro/venv/lib/python3.4/site-packages/tablib/packages/dbfpy/fields.py__init__Ks*           zDbfFieldDef.__init__cCst|jt|jS)N)cmpr rr)rotherrrr__cmp__jszDbfFieldDef.__cmp__cCs t|jS)N)hashr )rrrr__hash__mszDbfFieldDef.__hash__cCset|dkstt|d}|tj|dd|t|d|||d|S)azDecode dbf field definition from the string data.
