Class DimacsArrayReader

java.lang.Object
  extended by org.sat4j.tools.DimacsArrayReader
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
ExtendedDimacsArrayReader

public class DimacsArrayReader
extends Object
implements Serializable

Very simple Dimacs array reader. Allow solvers to read the constraints from arrays that effectively contain Dimacs formatted lines (without the terminating 0). Adaptation of org.sat4j.reader.DimacsReader.

Constructor Detail

DimacsArrayReader

public DimacsArrayReader(ISolver solver)
Method Detail

handleConstr

protected boolean handleConstr(int gateType,
                               int output,
                               int[] inputs)
                        throws ContradictionException
Throws:
ContradictionException

parseInstance

public ISolver parseInstance(int[] gateType,
                             int[] outputs,
                             int[][] inputs,
                             int maxVar)
                      throws ContradictionException
Parameters:
gateType - gateType[i] is the type of gate i according to the Extended Dimacs specs; ignored in DimacsArrayReader, but important for inheriting classes
outputs - outputs[i] is the number of the output; ignored in DimacsArrayReader
inputs - inputs[i] contains the clauses in DimacsArrayReader; an overriding class might have it contain the inputs of the current gate
maxVar - the maximum number of assigned ids
Throws:
ContradictionException - si le probleme est trivialement inconsitant

decode

public String decode(int[] model)

getSolver

protected ISolver getSolver()
