Method Detail

extractConstraintWeight

public Score<?> extractConstraintWeight(Solution_ workingSolution)

createRule

public Rule createRule(<any> scoreHolderGlobal)

getConstraintFactory

public ConstraintFactory 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
