    - #### LESS_THAN

          public static final ComparisonOperator LESS_THAN

    - #### LESS_OR_EQUAL

  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static ComparisonOperator 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

    - #### getOperator

          public static ComparisonOperator getOperator​(java.lang.String str)
                                                throws java.lang.UnsupportedOperationException

      Throws:
        `java.lang.UnsupportedOperationException`

    - #### toADQL

          public java.lang.String toADQL()

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Enum<ComparisonOperator>`
