Enum SatParameters.Polarity

java.lang.Object

java.lang.Enum<SatParameters.Polarity>

com.google.ortools.sat.SatParameters.Polarity

All Implemented Interfaces:

com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, java.io.Serializable, java.lang.Comparable<SatParameters.Polarity>

Enclosing class:

SatParameters

public static enum SatParameters.Polarity
extends java.lang.Enum<SatParameters.Polarity>
implements com.google.protobuf.ProtocolMessageEnum

 Specifies the initial polarity (true/false) when the solver branches on a
 variable. This can be modified later by the user, or the phase saving
 heuristic.

 Note(user): POLARITY_FALSE is usually a good choice because of the
 "natural" way to express a linear boolean problem.

Method Detail

values

public static SatParameters.Polarity[] 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 (SatParameters.Polarity c : SatParameters.Polarity.values())
    System.out.println(c);

Returns:

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

valueOf

public static SatParameters.Polarity valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getNumber

public final int getNumber()

Specified by:

getNumber in interface com.google.protobuf.Internal.EnumLite

Specified by:

getNumber in interface com.google.protobuf.ProtocolMessageEnum

valueOf

@Deprecated
public static SatParameters.Polarity valueOf(int value)

Deprecated. Use forNumber(int) instead.

Parameters:

value - The numeric wire value of the corresponding enum entry.

Returns:

The enum associated with the given numeric wire value.

forNumber

public static SatParameters.Polarity forNumber(int value)

Parameters:

value - The numeric wire value of the corresponding enum entry.

Returns:

The enum associated with the given numeric wire value.
