# CommonEvent
> ![icon-note.gif](public_sys-resources/icon-note.gif) **NOTE**
The **CommonEvent** module provides common event capabilities, including the capabilities to publish, subscribe to, and unsubscribe from common events, as well obtaining and setting the common event result code and result data.
> **NOTE**
>
> The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.

| EaseInOut | The animation starts and ends at a low speed. The cubic-bezier curve (0.42, 0.0, 0.58, 1.0) is used. |
| FastOutSlowIn | The animation uses the standard cubic-bezier curve (0.4, 0.0, 0.2, 1.0). |
| LinearOutSlowIn | The animation uses the deceleration cubic-bezier curve (0.0, 0.0, 0.2, 1.0). |
| FastOutLinearIn | The animation uses the acceleration cubic-bezier curve (0.4, 0.0, 1.0, 1.0). |
| ExtremeDeceleration | The animation uses the extreme deceleration cubic-bezier curve (0.0, 0.0, 0.0, 1.0). |
| Sharp | The animation uses the sharp cubic-bezier curve (0.33, 0.0, 0.67, 1.0). |
| Rhythm | The animation uses the rhythm cubic-bezier curve (0.7, 0.0, 0.2, 1.0). |
