Class EfficientScanner

java.lang.Object
  org.sat4j.reader.EfficientScanner

All Implemented Interfaces:

Serializable

public class EfficientScanner
extends Object
implements Serializable

Efficient scanner based on the LecteurDimacs class written by Frederic Laihem. It is much faster than Java Scanner class because it does not split the input file into strings but reads and interpret the input char by char. Furthermore, it is based on stream (char in ASCII) and not reader (word in UTF).

Since:

2.1
