DroolsConstraintFactory

public DroolsConstraintFactory(SolutionDescriptor<Solution_> solutionDescriptor)

Method Detail

forEachIncludingNullVars

public <A> UniConstraintStream<A> forEachIncludingNullVars(Class<A> sourceClass)

Description copied from interface: ConstraintFactory

As defined by ConstraintFactory.forEach(Class), but without any filtering of null planning entity variables.

Type Parameters:

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

Parameters:

sourceClass - never null

Returns:

never null

fromUnfiltered

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

Description copied from interface: ConstraintFactory

This method is deprecated. Migrate uses of this method to ConstraintFactory.forEachIncludingNullVars(Class), but first understand that subsequent joins and conditional propagation calls (UniConstraintStream.ifExists(java.lang.Class<B>, org.optaplanner.core.api.score.stream.bi.BiJoiner<A, B>) etc.) will now also consistently filter out planning entities with null variables.

The original Javadoc of this method follows:

As defined by ConstraintFactory.from(Class), but without any filtering of uninitialized planning entities.

Type Parameters:

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

Parameters:

fromClass - never null

Returns:

never null

getSolutionDescriptor

public SolutionDescriptor<Solution_> getSolutionDescriptor()

Specified by:

getSolutionDescriptor in class InnerConstraintFactory<Solution_,DroolsConstraint<Solution_>>

Returns:

never null

getVariableFactory

public DroolsVariableFactory getVariableFactory()

getDefaultConstraintPackage

public String getDefaultConstraintPackage()

Description copied from interface: ConstraintFactory

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

Returns:

never null
