Constructor Details

DefaultPlanningVariableMetaModel

public DefaultPlanningVariableMetaModel(PlanningEntityMetaModel<Solution_,Entity_> entity,
 BasicVariableDescriptor<Solution_> variableDescriptor)

Creates an instance of a DefaultPlanningVariableMetaModel record class.

Parameters:

entity - the value for the entity record component

variableDescriptor - the value for the variableDescriptor record component

Method Details

type

public Class<Value_> type()

Description copied from interface: VariableMetaModel

Describes the type of the value that this variable can hold.

Specified by:

type in interface VariableMetaModel<Solution_,Entity_,Value_>

Returns:

never null

name

public String name()

Description copied from interface: VariableMetaModel

Describes the name of this variable, which is typically a field name in the entity.

Specified by:

name in interface VariableMetaModel<Solution_,Entity_,Value_>

Returns:

never null

allowsUnassigned

public boolean allowsUnassigned()

Description copied from interface: PlanningVariableMetaModel

Returns whether the planning variable allows null values.

Specified by:

allowsUnassigned in interface PlanningVariableMetaModel<Solution_,Entity_,Value_>

Returns:

true if the planning variable allows null values, false otherwise.

isChained

public boolean isChained()

Description copied from interface: PlanningVariableMetaModel

Returns whether the planning variable is chained.

Specified by:

isChained in interface PlanningVariableMetaModel<Solution_,Entity_,Value_>

Returns:

true if the planning variable is chained, false otherwise.

equals

public boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

hashCode

public int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

Returns:

a hash code value for this object

toString

public String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

entity

public PlanningEntityMetaModel<Solution_,Entity_> entity()

Returns the value of the entity record component.

Specified by:

entity in interface VariableMetaModel<Solution_,Entity_,Value_>

Returns:

the value of the entity record component

variableDescriptor

public BasicVariableDescriptor<Solution_> variableDescriptor()

Returns the value of the variableDescriptor record component.

Specified by:

variableDescriptor in interface InnerGenuineVariableMetaModel<Solution_>
