SolverFactory (OptaPlanner core 6.3.0.Final API)

java.lang.Object
- org.optaplanner.core.api.solver.SolverFactory

Direct Known Subclasses:

AbstractSolverFactory
```
public abstract class SolverFactory
extends Object
```
Builds Solver instances.
To build an instance, use createFromXmlResource(String) or any of the other creation methods.
Supports tweaking the configuration programmatically before a Solver instance is build.

Methods
Modifier and Type	Method and Description
`abstract Solver`	`buildSolver()` Creates a new `Solver` instance.
`static SolverFactory`	`createEmpty()` Useful to build configuration programmatically, although it's almost always recommended to instead load a partial configuration with `createFromXmlResource(String)` and configure the remainder programmatically with `getSolverConfig()`.
`static SolverFactory`	`createEmpty(ClassLoader classLoader)` See `createEmpty()`.
`static SolverFactory`	`createFromXmlFile(File solverConfigFile)`
`static SolverFactory`	`createFromXmlFile(File solverConfigFile, ClassLoader classLoader)`
`static SolverFactory`	`createFromXmlInputStream(InputStream in)`
`static SolverFactory`	`createFromXmlInputStream(InputStream in, ClassLoader classLoader)`
`static SolverFactory`	`createFromXmlReader(Reader reader)`
`static SolverFactory`	`createFromXmlReader(Reader reader, ClassLoader classLoader)`
`static SolverFactory`	`createFromXmlResource(String solverConfigResource)`
`static SolverFactory`	`createFromXmlResource(String solverConfigResource, ClassLoader classLoader)` See `createFromXmlResource(String)`.
`abstract SolverConfig`	`getSolverConfig()` Allows you to problematically change the `SolverConfig` at runtime before building the `Solver`.

  - createFromXmlInputStream
```
public static SolverFactory createFromXmlInputStream(InputStream in)
```
    Parameters:
    in - never null, gets closed
    
    Returns:
    never null
  - createFromXmlInputStream
```
public static SolverFactory createFromXmlInputStream(InputStream in,
                                     ClassLoader classLoader)
```
    Parameters:

                                ClassLoader classLoader)
```
    Parameters:
    reader - never null, gets closed
    classLoader - sometimes null, the ClassLoader to use for loading all resources and Classes, null to use the default ClassLoader
    
    Returns:
    never null
  - getSolverConfig
```
public abstract SolverConfig getSolverConfig()
```
    Allows you to problematically change the SolverConfig at runtime before building the Solver.
    
    Returns:
