## EventListener events 

Cache Events are exposed via the EventListener API.  Typical scenarios are below.

### Cache Hit

In the ideal scenario the cache can fulfill the request without any conditional call to the network.
This will skip the normal events such as DNS, connecting to the network, and downloading the response body.

    cancelLatch.await()

    val events = eventRecorder.eventSequence.filter { isConnectionEvent(it) }.map { it.name }
    eventRecorder.clearAllEvents()

    assertThat(events).startsWith("CallStart", "ConnectStart", "ConnectEnd", "ConnectionAcquired")
    if (cancelMode == CANCEL) {
      assertThat(events).contains("Canceled")
    } else {
      assertThat(events).doesNotContain("Canceled")
    }

        }

        ArtifactTransferEvent event = wrap(transferEvent);
        event.setDataBuffer(buffer);
        event.setDataOffset(0);
        event.setDataLength(length);
        event.setTransferredBytes(transferred);

        listener.transferProgress(event);
    }

    @Override
    public void transferStarted(TransferEvent transferEvent) {

	maps.Copy(ntargets, list.targets)
	return ntargets
}

// Send - sends events to targets identified by target IDs.
func (list *TargetList) Send(event Event, targetIDset TargetIDSet, sync bool) {
	if sync {
		list.sendSync(event, targetIDset)
	} else {
		list.sendAsync(event, targetIDset)
	}
}

func (list *TargetList) sendSync(event Event, targetIDset TargetIDSet) {
	var wg sync.WaitGroup
	for id := range targetIDset {
