Class Channel.NOfEvents

  • Enclosing class:
    Channel

    public static class Channel.NOfEvents
extends java.lang.Object
    NofEvents may be used with @see Channel.TransactionOptions.nOfEvents(NOfEvents) to control how reporting Peer service events and Eventhubs will complete the future acknowledging the transaction has been seen by those Peers.

    You can use the method @see nofNoEvents to create an NOEvents that will result in the future being completed immediately when the Orderer has accepted the transaction. Note in this case the transaction event will be set to null.

    NofEvents can add Peer Eventing services and Eventhubs that should complete the future. By default all will need to see the transactions to complete the future. The method @see setN(int) can set how many in the group need to see the transaction completion. Essentially setting it to 1 is any.

    NofEvents may also contain other NofEvent grouping. They can be nested.
