Interface SolutionIterator

public interface SolutionIterator

This is an interface that allows a user to search and to iterate through multiple solutions. The expected use:

 SolutionIterator iter = solver.solutionIterator();
 while(iter.hasNext()) {
   Solution solution = iter.next();
     ...
 }
 
 The method next() should not be called without checking that hasNext() returned true.

 

Method Summary

Modifier and Type	Method and Description
boolean	hasNext() Returns true if the iteration has more solutions.
Solution	next() Returns the next solution

Method Detail

hasNext

boolean hasNext()

Returns true if the iteration has more solutions. In other words, returns true if next would return an element rather than throwing an exception.

Returns:

true if the iteration has more solutions

next

Solution next()

Returns the next solution

Returns:

the next solution

Throws:

java.lang.RuntimeException - "Cannot use SolutionIterator.next() before checking that hasNext() returned true"
