Examples of co.cask.tigon.api.flow.flowlet.InputContext

co.cask.tigon.api.flow.flowlet.InputContext
Represents the context of the input data that is passed to {@link Flowlet} for processing.

    this.queueName = queueName;
    // Memorize the transformed Iterable so that decoder would only invoked once for each event no matter
    // how many times iterator() is called. This is to save time as well as a need for the case where
    // metrics has been logged inside the decoder.
    this.events = result.isEmpty() ? ImmutableList.<T>of() : ImmutableList.copyOf(Iterables.transform(result, decoder));
    this.inputContext = new InputContext() {
      @Override
      public String getOrigin() {
        return queueName.getSimpleName();
      }
