/**
* <p>
* Describes an adjustment based on the difference between the value of the
* aggregated CloudWatch metric and the breach threshold that you've defined for
* the alarm.
* </p>
* <p>
* For the following examples, suppose that you have an alarm with a breach
* threshold of 50:
* </p>
* <ul>
* <li>
* <p>
* If you want the adjustment to be triggered when the metric is greater than or
* equal to 50 and less than 60, specify a lower bound of 0 and an upper bound
* of 10.
* </p>
* </li>
* <li>
* <p>
* If you want the adjustment to be triggered when the metric is greater than 40
* and less than or equal to 50, specify a lower bound of -10 and an upper bound
* of 0.
* </p>
* </li>
* </ul>
* <p>
* There are a few rules for the step adjustments for your step policy:
* </p>
* <ul>
* <li>
* <p>
* The ranges of your step adjustments can't overlap or have a gap.
* </p>
* </li>
* <li>
* <p>
* At most one step adjustment can have a null lower bound. If one step
* adjustment has a negative lower bound, then there must be a step adjustment
* with a null lower bound.
* </p>
* </li>
* <li>
* <p>
* At most one step adjustment can have a null upper bound. If one step
* adjustment has a positive upper bound, then there must be a step adjustment
* with a null upper bound.
* </p>
* </li>
* <li>
* <p>
* The upper and lower bound can't be null in the same step adjustment.
* </p>
* </li>
* </ul>
