Enum 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
