ai.timefold.solver.core.impl.score.director.AbstractScoreDirector.AbstractScoreDirectorBuilder<Solution_,Score_,Factory_,Builder_>

Type Parameters:

Solution_ - The type of the planning solution.

Score_ - The type of the score associated with the solution.

Factory_ - The type of the score director factory used to create the score director.

Builder_ - The type of the builder, used for fluent configuration.

Direct Known Subclasses:

public abstract static class AbstractScoreDirector.AbstractScoreDirectorBuilder<Solution_,Score_ extends Score<Score_>,Factory_ extends AbstractScoreDirectorFactory<Solution_,Score_,Factory_>,Builder_ extends AbstractScoreDirector.AbstractScoreDirectorBuilder<Solution_,Score_,Factory_,Builder_>>
extends Object

An abstract builder for creating instances of InnerScoreDirector. This class provides methods to configure the behavior of the score director before building it. Unless the appropriate withers are called, the score director will be built:

• With ConstraintMatchPolicy.DISABLED.
• With lookup disabled.
• Expecting shadow variables in their correct state.

build

public abstract AbstractScoreDirector<Solution_,Score_,Factory_> build()

buildDerived

public AbstractScoreDirector<Solution_,Score_,Factory_> buildDerived()

Optionally makes the score director a derived one; most score directors do not require this. Derived score directors may make choices which the main score director cannot make, such as reducing logging. Derived score directors are typically used for multithreaded solving, testing and assert modes. Derived score directors do not support move streams, as they are only used to calculate the score.
