The DSI utilities are a mish mash of classes accumulated during the last ten years in projects developed at the former DSI (Dipartimento di Scienze dell'Informazione, i.e., Information Sciences Department), now DI (Dipartimento di Informatica, i.e., Informatics Department) of the Università degli Studi di Milano. They were originally distributed in several projects (mainly in MG4J) but we finally decided to gather all the material in a single place.

The DSI utilities are free software distributed under either the GNU Lesser General Public License 2.1+ or the Apache Software License 2.0.


The implementations available are a bit eclectic due to the particular kind of applications we developed. Very broadly, we have:

General utilities
I/O big classes
Collections and similar big classes
Main classes manipulating bits
Word-based compression/decompression classes
I/O classes
Basic classes
Logging classes
A fast, lightweight, on-demand (X)HTML parser
Callbacks for the BulletParser
Statistics classes
Miscellaneous utility classes
Concurrent data structures
