FD.Broadcaster

java.lang.Object
- org.jgroups.protocols.FD.Broadcaster

Enclosing class:

FD
```
protected final class FD.Broadcaster
extends java.lang.Object
```
Task that periodically broadcasts a list of suspected members to the group. Goal is not to lose a SUSPECT message: since these are bcast unreliably, they might get dropped. The BroadcastTask makes sure they are retransmitted until a view has been received which doesn't contain the suspected members any longer. Then the task terminates.
