Modifier and Type	Method	Description
ConstraintSessionFactory<Solution_>	buildSessionFactory(Constraint[] constraints)	This method is thread-safe.
<A> UniConstraintStream<A>	fromUnfiltered(Class<A> fromClass)	Like ConstraintFactory.from(Class), but without any filtering of uninitialized planning entities.
String	getDefaultConstraintPackage()	This is ConstraintConfiguration.constraintPackage() if available, otherwise the package of the PlanningSolution class.
SolutionDescriptor<Solution_>	getSolutionDescriptor()
LongSupplier	getVariableIdSupplier()	In order to guarantee that all variables have unique names within the context of a rule, we need to be able to uniquely identify them.

Constructor Detail

DroolsConstraintFactory

public DroolsConstraintFactory(SolutionDescriptor<Solution_> solutionDescriptor)

Method Detail

fromUnfiltered

public <A> UniConstraintStream<A> fromUnfiltered(Class<A> fromClass)

Description copied from interface: ConstraintFactory

Like ConstraintFactory.from(Class), but without any filtering of uninitialized planning entities.

Specified by:

fromUnfiltered in interface ConstraintFactory

Type Parameters:

A - the type of the matched problem fact or planning entity

Parameters:

fromClass - never null

Returns:

never null

buildSessionFactory

public ConstraintSessionFactory<Solution_> buildSessionFactory(Constraint[] constraints)

Description copied from interface: InnerConstraintFactory

This method is thread-safe.

Specified by:

buildSessionFactory in interface InnerConstraintFactory<Solution_>

Parameters:

constraints - never null

Returns:

never null

getSolutionDescriptor

public SolutionDescriptor<Solution_> getSolutionDescriptor()

Specified by:

getSolutionDescriptor in interface InnerConstraintFactory<Solution_>

Returns:

never null

getVariableIdSupplier

public LongSupplier getVariableIdSupplier()

In order to guarantee that all variables have unique names within the context of a rule, we need to be able to uniquely identify them. This ID supplier is used by all variable-creating code.

Returns:

supplier that returns a unique number each time it is invoked

getDefaultConstraintPackage

public String getDefaultConstraintPackage()

Description copied from interface: ConstraintFactory

This is ConstraintConfiguration.constraintPackage() if available, otherwise the package of the PlanningSolution class.

Specified by:

getDefaultConstraintPackage in interface ConstraintFactory

Returns:

never null
