List of nextSolution() Examples

Examples of nextSolution()

com.hp.hpl.jena.query.ResultSet.nextSolution()
Moves onto the next result (legacy - use .next()).
com.hp.hpl.jena.query.ResultSetRewindable.nextSolution()
jpl.Query.nextSolution()
solver.Solver.nextSolution()
Once {@link Solver#findSolution()} has been called once, other solutions can be found using this method.
The search is then resume to the last found solution point. @return a boolean stating whereas a new solution has been found (true), or not (false).
