## Interface FallThroughCapableMailbox

- All Superinterfaces:
    `Clearable`, `IGroupable`, `Mailbox`

      public interface FallThroughCapableMailbox
      extends Mailbox

  A fall through capable mailbox can directly call the update method of its `Receiver` instead of using the standard post-deliver mailbox semantics. If the fall through flag is set to true, the mailbox uses direct delivery, otherwise it operates in the original behavior. The fall through operation is preferable whenever applicable because it improves performance. The fall through flag is controlled by the `CommunicationTracker` based on the receiver node type and network topology.
