java.lang.Enum<AbstractCriterion.ValueUpdateType>

org.cpsolver.ifs.criteria.AbstractCriterion.ValueUpdateType

All Implemented Interfaces:

Serializable, Comparable<AbstractCriterion.ValueUpdateType>

Enclosing class:

AbstractCriterion<V extends Variable<V,T>,T extends Value<V,T>>

protected static enum AbstractCriterion.ValueUpdateType
extends Enum<AbstractCriterion.ValueUpdateType>

Defines how the overall value of the criterion should be automatically updated (using Criterion.getValue(Value, Set)).

Enum Constant Detail

BeforeUnassignedBeforeAssigned

public static final AbstractCriterion.ValueUpdateType BeforeUnassignedBeforeAssigned

Update is done before an unassignment (decrement) and before an assignment (increment).

AfterUnassignedBeforeAssigned

public static final AbstractCriterion.ValueUpdateType AfterUnassignedBeforeAssigned

Update is done after an unassignment (decrement) and before an assignment (increment).

BeforeUnassignedAfterAssigned

public static final AbstractCriterion.ValueUpdateType BeforeUnassignedAfterAssigned

Update is done before an unassignment (decrement) and after an assignment (increment).

AfterUnassignedAfterAssigned

public static final AbstractCriterion.ValueUpdateType AfterUnassignedAfterAssigned

Update is done after an unassignment (decrement) and after an assignment (increment). This is the default.

NoUpdate

public static final AbstractCriterion.ValueUpdateType NoUpdate

Criterion is to be updated manually (e.g., using Criterion.inc(Assignment, double)).

Method Detail

values

public static AbstractCriterion.ValueUpdateType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AbstractCriterion.ValueUpdateType c : AbstractCriterion.ValueUpdateType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AbstractCriterion.ValueUpdateType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
