Enum Condition

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Condition>
    public enum Condition
extends java.lang.Enum<Condition>
    Represents the collection of valid threshold conditions that can be used to define a ScalingRule.
    See Also:
    ScalingRule

      Enum Constants 
      Enum Constant Description
      ABOVE
      Scaling rule condition that triggers when the metric value is above the threshold.
      BELOW
      Scaling rule condition that triggers when the metric value is below the threshold.
      EXACTLY
      Scaling rule condition that triggers when the metric value has the same value as the threshold.

      • values

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

      • valueOf

        public static Condition 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

      • evaluate

        public boolean evaluate​(java.lang.Double a,
                        java.lang.Double b)
        Evaluates the condition on two values in in-fix notation: a Condition b. For example a > b.
        Parameters:
        a - The left-hand value
        b - The right-hand value.
        Returns:
        true if the condition is satisfied, false otherwise.
