FIXME: docs and examples needed (dont' forget to tell about problems adding new fields on the fly) Implementation notes: ``_new`` field is used to indicate whether this is a new data table. `addField` could be used only for the new tables! If at least one record was appended to the table it's structure couldn't be changed. )namerstream_changed_new_ignore_errorsct|tr9||_|rt|d|_n7t|dt ||_nt |dd|_||_|r|j|_n*|jj|j|_||_ t ||_ d|_ y)afInitialize instance. Arguments: f: Filename or file-like object. new: True if new data table must be created. Assume data table exists if this argument is False. readOnly: if ``f`` argument is a string file will be opend in read-only mode; in other cases this argument is ignored. This argument is ignored even if ``new`` argument is True. headerObj: `header.DbfHeader` instance or None. If this argument is None, new empty header will be used with the all fields set by default. ignoreErrors: if set, failing field value conversion will return ``INVALID_VALUE`` instead of raising conversion error. zw+b)zr+brbr FN) isinstancestrr openr boolgetattr HeaderClassr fromStream ignoreErrorsrr )selffreadOnlynewrs O/var/www/horilla/myenv/lib/python3.12/site-packages/tablib/_vendor/dbfpy/dbf.py__init__z Dbf.__init__]s. a DI#1en #1mDN&CD  62.DIDK **,DK**55dkkBDK(I  c.|jjSN)r closedrs rz Dbf.s4;;#5#5r!c.|jjSr#)r recordCountr%s rr&z Dbf.s (?(?r!ch|jjDcgc]}|jc}Scc}wr#)rfieldsr )r_flds rr&z Dbf.s"DKK,>,>?Ddii??s/c.|jjSr#)rr*r%s rr&z Dbf.sdkk&8&8r!cJ|jxs|jjSr#)r rchangedr%s rr&z Dbf.sDMM$HT[[5H5Hr!cFt|x|j_|_y)z8Update `ignoreErrors` flag on the header object and selfN)rrrr)rvalues rrzDbf.ignoreErrorss9=eD  4#6r!c|jSr#)rr%s rr&z Dbf.s T((r!zError processing mode for DBF field value conversion if set, failing field value conversion will return ``INVALID_VALUE`` instead of raising conversion error. )docct|ts td|dkr|t|dzz }|t|k\r t d|S)aReturn fixed index.
