Enum SolutionType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<SolutionType>
    public enum SolutionType
extends java.lang.Enum<SolutionType>
    This enumeration defines the different types of results that the two-phase method returns.

    • Method Detail

      • values

        public static SolutionType[] 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 (SolutionType c : SolutionType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static SolutionType 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

      • getValue

        public java.lang.String getValue()
        Retrieves the value associated with the enumeration.
        Returns:
        The value associated with the enumeration.

      • toString

        public java.lang.String toString()
        Returns a string representation of the enumeration value.
        Overrides:
        toString in class java.lang.Enum<SolutionType>
        Returns:
        A string representation of the enumeration value.
