For more information about dbf header format visit `http://www.clicketyclick.dk/databases/xbase/format/dbf.html#DBF_STRUCT` Examples: Create an empty dbf header and add some field definitions: dbfh = DbfHeader() dbfh.addField(("name", "C", 10)) dbfh.addField(("date", "D")) dbfh.addField(DbfNumericFieldDef("price", 5, 2)) Create a dbf header with field definitions: dbfh = DbfHeader([ ("name", "C", 10), ("date", "D"), DbfNumericFieldDef("price", 5, 2), ]) ) signaturer lastUpdate recordLength recordCount headerLengthchanged_ignore_errorsNc||_|g|_nt||_t||_||_||_||_||_t|j|_ y)aInitialize instance. Arguments: fields: a list of field definitions; recordLength: size of the records; headerLength: size of the header; recordCount: number of records stored in DBF; signature: version number (aka signature). using 0x03 as a default meaning "File without DBT". for more information about this field visit ``http://www.clicketyclick.dk/databases/xbase/format/dbf.html#DBF_NOTE_1_TARGET`` lastUpdate: date of the DBF's update. this could be a string ('yymmdd' or 'yyyymmdd'), timestamp (int or float), datetime/date value, a sequence (assuming (yyyy, mm, dd, ...)) or an object having callable ``ticks`` field. ignoreErrors: error processing mode for DBF fields (boolean) N) r rlistrr r rr ignoreErrorsboolr)selfrrr rr r rs R/var/www/horilla/myenv/lib/python3.12/site-packages/tablib/_vendor/dbfpy/header.py__init__zDbfHeader.__init__:s`4# >DKv,DK!*-((&(DKK( c\|jtjt|S)z.Return header instance from the string object.) fromStreamioStringIOstr)clsstrings r fromStringzDbfHeader.fromStringcs~~bkk#f+677rc P|jd|jd}t|tst|t j }|}t jd|dd\}}}|d}|dkr|dz }n|d z }|d ||||d||d |d f}d} |jd}|d k7rp||jdz }tj|dj|| } |j| | j} |jd}|d k7rp|S)z%Return header object from the stream.r zzDbfHeader.s!5!5rc.|jjSrB)r monthrDs rrEzDbfHeader.s$//"7"7rc.|jjSrB)r dayrDs rrEzDbfHeader.s 3 3rcXt|x|_}|jD] }||_ y)z1Update `ignoreErrors` flag on self and all fieldsN)rrrr)rvalue_fields rrzDbfHeader.ignoreErrorss.&*5k1ekk (F"'F  (rc|jSrB)rrDs rrEzDbfHeader.s T((rzError processing mode for DBF field value conversion if set, failing field value conversion will return ``INVALID_VALUE`` instead of raising conversion error. )docc d}||j|j|j|j|jfz}|dj |j Dcgc]}d|jzc}z }|Scc}w)NzVersion (signature): 0x%02x Last update: %s Header length: %d Record length: %d Record count: %d FieldName Type Len Dec  z%10s %4s %3s %3s)r r rr rjoinr fieldInfo)r_rvr@s r__repr__zDbfHeader.__repr__sT^^T__d6G6G&&(8(8:: tyy?C{{ Kt $.."2 2 K    LsA> cBg}d}|D]}t|tjr|}nAt|dzdd\}}}} tj|} | ||| |j }||j z }|j||xj|z c_|S)ahInternal variant of the `addField` method. This method doesn't set `self.changed` field to True. Return value is a length of the appended records. Note: this method doesn't modify ``recordLength`` and ``headerLength`` fields.
