Java-CSV-Library

ACSVL - little lib provides find, edit and add methods to TXT data files, such as CSV.

• find methods - collection of methods allowing you to search by whole lines or just in single column. Some of them can return number of found line and line itself, and another can consume found line with its number in your special way.
• edit methods - to replace specific lines with your ones.
• add methods - to add one or collection of lines to the end of file.

• searchString - what to search
• startRaw - points on which raw to start searching

Important : All methods in the library might throw AcsvlException !

AcsvlException is all-in-one exception, it proxies other exceptions (e.g. FileNotFoundException, IOException, AcsvlFileFormatException, AcsvlInputFormatException) which can be reached by call getCause() method
