java.lang.Enum<MPModelRequest.SolverType>

com.google.ortools.linearsolver.MPModelRequest.SolverType

All Implemented Interfaces:

com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, java.io.Serializable, java.lang.Comparable<MPModelRequest.SolverType>

Enclosing class:

MPModelRequest

public static enum MPModelRequest.SolverType
extends java.lang.Enum<MPModelRequest.SolverType>
implements com.google.protobuf.ProtocolMessageEnum

 The solver type, which will select a specific implementation, and will also
 impact the interpretation of the model (i.e. are we solving the problem
 as a mixed integer program or are we relaxing it as a continuous linear
 program?).
 This must remain consistent with MPSolver::OptimizationProblemType.

Method Detail

values

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

Returns:

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

valueOf

public static MPModelRequest.SolverType 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
