</p>
<p>You can't create one of these elements directly, but several other elements inherit the methods and properties of these elements.</p>
<p>There are several predefined enumerations and constants provided in this class:</p>
<p>1. Duration This enum describes the possible predefined duration types. Generally a specific value in milliseconds can be supplied instead of one of these values.</p>
<ul>
<li>Feedback.Infinite - Infinite effect duration</li>
</ul>
<p>2. State This enum describes the state of the effect. An effect will be in one of these states.</p>
<ul>
<li>Feedback.Stopped - The effect is not running. This is the initial state.</li>
<li>Feedback.Paused - The effect is paused.</li>
<li>Feedback.Running - The effect is running.</li>
<li>Feedback.Loading - The effect is loading.</li>
</ul>
<p>3. ErrorType This enum describes the possible errors happening on the effect.</p>
<ul>
<li>Feedback.UnknownError - An unknown error occurred.</li>
<li>Feedback.DeviceBusy - The feedback could not start because the device is busy, the device could be busy if a higher-priority client is using the haptics/actuator device.</li>
</ul>
