Class LecteurDimacs

java.lang.Object
  org.sat4j.reader.Reader
      org.sat4j.reader.LecteurDimacs

All Implemented Interfaces:

java.io.Serializable

public class LecteurDimacs
extends Reader
implements java.io.Serializable

Dimacs Reader written by Frederic Laihem. It is much faster than DimacsReader because it does not split the input file into strings but reads and interpret the input char by char. Hence, it is a bit more difficult to read and to modify than DimacsReader. This reader is used during the SAT Competitions.
