Package com.dna.jopt.member.unit.condition.type

Class TypeConstraint

java.lang.Object

com.dna.jopt.member.unit.condition.type.TypeConstraint

All Implemented Interfaces:

IConstraint, Serializable

public class TypeConstraint
extends Object
implements IConstraint

This class allows setting IConstraint on INode. A IResource needs to have the matching TypeQualification in order to give service to said Node.

Implementation example:

 //Defining a Node
 CapacityResource jack = new CapacityResource(
             "JackEssenQualified",
             51.45,
             7.01667,
             Duration.ofHours(10),
             Quantities.getQuantity(1200, KILO(METRE)),
             workingHours);
     rep1.setCost(100, 1, 1);

 // Defining a qualification and giving it to the Node
     TypeQualification typeQualification1 = new TypeQualification();
     typeQualification1.addType("plumbing");
     jack.addQualification(typeQualification1);

     opti.addElement(jack);

 // Defining a Constraint
 IConstraint typeConstraint = new TypeConstraint();
 ((TypeConstraint) typeConstraint).addType("plumbing");
 typeConstraint.setIsHard(true);

 Duration visitDuration = Duration.ofMinutes(20);

 // Defining a Node and giving it the Constraint
 TimeWindowGeoNode aachen =
 new TimeWindowGeoNode("Aachen", 50.775346, 6.083887, weeklyOpeningHours, visitDuration, 1);
 aachen.addConstraint(typeConstraint);
 this.addElement(aachen);

TypeConstraint

public TypeConstraint()

Method Details

getTitle

public String getTitle()

Description copied from interface: IConstraint

Gets the title of the constraint.

Specified by:

getTitle in interface IConstraint

Returns:

the title

isHard

public boolean isHard()

Description copied from interface: IConstraint

Checks the parameter or directly returns true where this must be the case.

Specified by:

isHard in interface IConstraint

Returns:

the value of the checked boolean

setIsHard

public void setIsHard(boolean isHard)

Description copied from interface: IConstraint

Sets the constraint to hard if the respective parameter is given or returns an IllegalStateException if this is expected but not the case.

Specified by:

setIsHard in interface IConstraint

Parameters:

isHard - the boolean to be set

isSatisfied

public boolean isSatisfied(com.dna.jopt.assessment.costassessor.IEntityCostAssessor ca,
 INode node,
 ILogicEntityRoute route)

Description copied from interface: IConstraint

Filters out hard constraint mismatches by checking whether a Node demands a Qualification as a hard constraint but the Resource does not provide this one. The idea is to have only soft constraints problems in the optimisation which can get solved by adding cost.

Specified by:

isSatisfied in interface IConstraint

Parameters:

ca - the iEntityCostAssessor

node - the iNode

route - the iLogicEntityRoute

Returns:

the boolean whether the route is satisfied. True means no problems detected

assessConstraint

public com.dna.jopt.assessment.costassessorrestriction.restrictionresult.IEntityRestrictionResult assessConstraint(IEntity en,
 ILogicEntityRoute route,
 INode node,
 com.dna.jopt.assessment.costadjustment.IEntityCostAdjuster cad,
 com.dna.jopt.assessment.costassessor.IEntityCostAssessor ca,
 com.dna.jopt.framework.inputplausibility.properties.IPropertyProvider propertyProvider,
 boolean resultRequested)

Description copied from interface: IConstraint

Assesses the route, checking if the appropriate qualifications for the constraints are present.

The boolean true saves the data.

Specified by:

assessConstraint in interface IConstraint

Parameters:

en - entity

route - the iLogicEntityRoute

node - node

cad - iEntityCostAdjuster

ca - ca

propertyProvider - iPropertyProvider

resultRequested - the boolean whether to save the results of the route

Returns:

Entity Restriction Result

toString

public String toString()

Overrides:

toString in class Object

addType

public void addType(String type)

getTypes

public List<String> getTypes()

setTypes

public void setTypes(List<String> types)

hasMembers

public boolean hasMembers()

Specified by:

hasMembers in interface IConstraint
