public class BinFileStrColPreparer

extends Object

This class prepares the two tempFiles which are needed to access word_bins faster. It takes the wordlist file as input, which first must be dumped from the database via the following command: select w.wort_nr, w.wort_bin into outfile '/var/roedel/ksim/wortliste.dump' from wortliste w order by w.wort_nr asc; The file must be in the working directory of this program under data/ksim/ or as specified. Assumes that wordnumers in the first column are mostly wothout holes. It will fill up useless 4 bytes per missing wordnumber up to the next existing wordnumber in the indexfile Format of first file: char[?] of words Format of second file: char[4] Semantics: nth 4-byte-number gives location of end of collocationsnumbers of the wordnumber n. Begin is stored at n-1 ASSUMPTIONS: column1: wordNrs don't have too large 'holes'
