Enum Constant Detail

UNKNOWN

public static final CpSolverStatus UNKNOWN

 The status of the model is still unknown. A search limit has been reached
 before any of the statuses below could be determined.
 

UNKNOWN = 0;

MODEL_INVALID

public static final CpSolverStatus MODEL_INVALID

 The given CpModelProto didn't pass the validation step. You can get a
 detailed error by calling ValidateCpModel(model_proto).
 

MODEL_INVALID = 1;

FEASIBLE

public static final CpSolverStatus FEASIBLE

 A feasible solution has been found. But the search was stopped before we
 could prove optimality or before we enumerated all solutions of a
 feasibility problem (if asked).
 

FEASIBLE = 2;

INFEASIBLE

public static final CpSolverStatus INFEASIBLE

 The problem has been proven infeasible.
 

INFEASIBLE = 3;

OPTIMAL

public static final CpSolverStatus OPTIMAL

 An optimal feasible solution has been found.

 More generally, this status represent a success. So we also return OPTIMAL
 if we find a solution for a pure feasibility problem or if a gap limit has
 been specified and we return a solution within this limit. In the case
 where we need to return all the feasible solution, this status will only be
 returned if we enumerated all of them; If we stopped before, we will return
 FEASIBLE.
 

OPTIMAL = 4;

UNRECOGNIZED

public static final CpSolverStatus UNRECOGNIZED

Field Detail

UNKNOWN_VALUE

public static final int UNKNOWN_VALUE

 The status of the model is still unknown. A search limit has been reached
 before any of the statuses below could be determined.
 

UNKNOWN = 0;

MODEL_INVALID_VALUE

public static final int MODEL_INVALID_VALUE

 The given CpModelProto didn't pass the validation step. You can get a
 detailed error by calling ValidateCpModel(model_proto).
 

MODEL_INVALID = 1;

FEASIBLE_VALUE

public static final int FEASIBLE_VALUE

 A feasible solution has been found. But the search was stopped before we
 could prove optimality or before we enumerated all solutions of a
 feasibility problem (if asked).
 

FEASIBLE = 2;

INFEASIBLE_VALUE

public static final int INFEASIBLE_VALUE

 The problem has been proven infeasible.
 

INFEASIBLE = 3;

OPTIMAL_VALUE

public static final int OPTIMAL_VALUE

 An optimal feasible solution has been found.

 More generally, this status represent a success. So we also return OPTIMAL
 if we find a solution for a pure feasibility problem or if a gap limit has
 been specified and we return a solution within this limit. In the case
 where we need to return all the feasible solution, this status will only be
 returned if we enumerated all of them; If we stopped before, we will return
 FEASIBLE.

Method Detail

values

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

Returns:

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

valueOf

public static CpSolverStatus 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 CpSolverStatus 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 CpSolverStatus forNumber(int value)

Parameters:

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

Returns:

The enum associated with the given numeric wire value.
