Enum Constant Summary

Enum Constants

Enum Constant and Description
COMBINED_FACTOR Alternatives are factored where possible; results are combined, and both factored and unfactored alternatives are included in the result.
FULL_FACTOR Factors all alternatives of the decision.
PARTIAL_FACTORED Attempts to factor all alternatives of the decision.
PARTIAL_UNFACTORED Attempts to factor all alternatives of the decision, and returns the remaining unfactored alternatives.

Enum Constant Detail

COMBINED_FACTOR

public static final LeftFactoringRuleTransformer.DecisionFactorMode COMBINED_FACTOR

Alternatives are factored where possible; results are combined, and both factored and unfactored alternatives are included in the result.

FULL_FACTOR

public static final LeftFactoringRuleTransformer.DecisionFactorMode FULL_FACTOR

Factors all alternatives of the decision. The factoring fails if the decision contains one or more alternatives which cannot be factored.

PARTIAL_FACTORED

public static final LeftFactoringRuleTransformer.DecisionFactorMode PARTIAL_FACTORED

Attempts to factor all alternatives of the decision. Alternatives which could not be factored are not included in the result.

PARTIAL_UNFACTORED

public static final LeftFactoringRuleTransformer.DecisionFactorMode PARTIAL_UNFACTORED

Attempts to factor all alternatives of the decision, and returns the remaining unfactored alternatives. Alternatives which could be factored are not included in the result.

Method Detail

values

public static LeftFactoringRuleTransformer.DecisionFactorMode[] 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 (LeftFactoringRuleTransformer.DecisionFactorMode c : LeftFactoringRuleTransformer.DecisionFactorMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static LeftFactoringRuleTransformer.DecisionFactorMode 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
