Modifier and Type	Method and Description
Solver<Solution_>	buildSolver() Creates a new Solver instance.
SolverFactory<Solution_>	cloneSolverFactory() Build a SolverFactory quickly (without parsing XML) that builds the exact same Solver with SolverFactory.buildSolver(), but can also be modified with SolverFactory.getSolverConfig() to build a different Solver without affecting the original SolverFactory.
SolverConfig	getSolverConfig() Allows you to programmatically change the SolverConfig at runtime before building the Solver.

Method Detail

getSolverConfig

public SolverConfig getSolverConfig()

Description copied from class: SolverFactory

Allows you to programmatically change the SolverConfig at runtime before building the Solver.

This method is not thread-safe. To configure a SolverConfig differently for parallel requests, build a template SolverFactory from XML and clone it SolverFactory.cloneSolverFactory() for each request, before before calling this method.

Specified by:

getSolverConfig in class SolverFactory<Solution_>

Returns:

never null

buildSolver

public Solver<Solution_> buildSolver()

Description copied from class: SolverFactory

Creates a new Solver instance.

Specified by:

buildSolver in class SolverFactory<Solution_>

Returns:

never null

cloneSolverFactory

public SolverFactory<Solution_> cloneSolverFactory()

Description copied from class: SolverFactory

Build a SolverFactory quickly (without parsing XML) that builds the exact same Solver with SolverFactory.buildSolver(), but can also be modified with SolverFactory.getSolverConfig() to build a different Solver without affecting the original SolverFactory.

Specified by:

cloneSolverFactory in class SolverFactory<Solution_>

Returns:

never null, often a different SolverFactory subclass implementation than this instance
