public final class FallbackIndicationManager
extends Manager

Smacks API for XEP-0428: Fallback Indication. In some scenarios it might make sense to mark the body of a message as fallback for legacy clients. Examples are encryption mechanisms where the sender might include a hint for legacy clients stating that the body (eg. "This message is encrypted") should be ignored.
