Static buffer data will automatically stored when it comes to foreground.
This interface is used to indicate whether external data needs to be used to update the buffer(false) instead of using the default stored data(true).
- Parameters
-
needDefaultStoredData | Specifies whether to use the default stored data. |
Implements Buffer.
