WARNING: Release 2.0 has minor binary incompatibilities with previous
releases, mainly due to the move from the interface
it.unimi.dsi.util.LongBigList to the now standard
it.unimi.dsi.fasutil.longs.LongBigList.
It is part of a parallel release
of fastutil, the DSI Utilities,
Sux4J, MG4J, WebGraph, etc. that were
all modified to fit the new interface, and that prepare the way for our
"big" versions, that is, supporting >231 entries in arrays (simulated),
elements in lists, terms, documents, nodes, etc. Please read our (short)
"Moving Java to Big Data" document for details.
Introduction
The DSI
utilities are a mish mash of classes accumulated during the last
ten years in projects developed at the DSI (Dipartimento di Scienze dell'Informazione,
e.g., Information Sciences 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 distributed under the GNU Lesser General Public License.
Installation
You can grab the DSI Utilities from
Maven Central.
Otherwise, you have to install the
.jar file coming with the distribution and the dependencies, which are gathered for your convenience
in a tarball.
