Method Details

values

public static ConstraintMatchPolicy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ConstraintMatchPolicy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

match

public static ConstraintMatchPolicy match(ScoreAnalysisFetchPolicy scoreAnalysisFetchPolicy)

To achieve the most performance out of the underlying solver, the policy should match whatever policy was used for score analysis. For example, if the fetch policy specifies that only match counts are necessary and not matches themselves (ScoreAnalysisFetchPolicy.FETCH_MATCH_COUNT), we can configure the solver to not produce justifications (ENABLED_WITHOUT_JUSTIFICATIONS).

Parameters:

scoreAnalysisFetchPolicy -

Returns:

Match policy best suited for the given fetch policy.

isEnabled

public boolean isEnabled()

isJustificationEnabled

public boolean isJustificationEnabled()
