Class SolutionCollector

java.lang.Object
com.google.ortools.constraintsolver.BaseObject
com.google.ortools.constraintsolver.SearchMonitor
com.google.ortools.constraintsolver.SolutionCollector
public class SolutionCollector
extends SearchMonitor
This class is the root class of all solution collectors.
It implements a basic query API to be used independently
of the collector used.

      public void enterSearch()
      Beginning of the search.
      Overrides:
      enterSearch in class SearchMonitor

    • solutionCount

      public int solutionCount()
      Returns how many solutions were stored during the search.

    • solution

      public Assignment solution​(int n)
      Returns the nth solution.

    • wallTime

      public long wallTime​(int n)
      Returns the wall time in ms for the nth solution.

    • branches

      public long branches​(int n)
      Returns the number of branches when the nth solution was found.

    • failures

      public long failures​(int n)
      Returns the number of failures encountered at the time of the nth
      solution.

    • objectiveValue

      public long objectiveValue​(int n)
      Returns the objective value of the nth solution.

    • value

      public long value​(int n, IntVar var)
      This is a shortcut to get the Value of 'var' in the nth solution.

    • startValue

      public long startValue​(int n, IntervalVar var)
      This is a shortcut to get the StartValue of 'var' in the nth solution.

    • endValue

      public long endValue​(int n, IntervalVar var)
      This is a shortcut to get the EndValue of 'var' in the nth solution.
