                        DroolsAbstractConstraintStream<Solution_> scoringStream)

Method Detail

extractConstraintWeight

public Score<?> extractConstraintWeight(Solution_ workingSolution)

createRule

public org.drools.model.Rule createRule(org.drools.model.Global<? extends AbstractScoreHolder<?>> scoreHolderGlobal)

getConstraintFactory

public DroolsConstraintFactory<Solution_> getConstraintFactory()

Description copied from interface: Constraint

The ConstraintFactory that build this.

Specified by:

getConstraintFactory in interface Constraint

Returns:

never null

getConstraintPackage

public String getConstraintPackage()

Description copied from interface: Constraint

The constraint package is the namespace of the constraint.

When using a ConstraintConfiguration, it is equal to the ConstraintWeight.constraintPackage().

Specified by:

getConstraintPackage in interface Constraint

Returns:

never null

getConstraintName

public String getConstraintName()

Description copied from interface: Constraint

The constraint name. It might not be unique, but Constraint.getConstraintId() is unique.

When using a ConstraintConfiguration, it is equal to the ConstraintWeight.value().

Specified by:

getConstraintName in interface Constraint

Returns:

never null

getExpectedJustificationTypes

public Class[] getExpectedJustificationTypes()

As defined by DroolsRuleStructure.getExpectedJustificationTypes().

Returns:

never null, never empty

toString

public String toString()

Overrides:

toString in class Object
