Olm Power Down Task

Olm Power Down Task

A task capable of running in parallel powering down OLM power.
The package also contains an Interface left open to be implemented
at a later time.

Pseudo code example usage:

ListenableFuture<OLMRenderingResult> futureAtoZ =
    this.executor.submit(
        new OlmPowerTurnDownTask(...)
    );

ListenableFuture<OLMRenderingResult> futureZtoA =
    this.executor.submit(
        new OlmPowerTurnDownTask(...)
    );

ListenableFuture<List<OLMRenderingResult>> futures =
    Futures.allAsList(futureAtoZ, futureZtoA);

List<OLMRenderingResult> results;

try{
    results = futures.get(Timeouts.OLM_TIMEOUT, TimeUnit.MILLISECONDS);
} catch (Exception e) {
    LOG.error("Error while turning down power!");
}

if (results.get(0).isSuccess() && results.get(1).isSuccess()) {
    LOG.info("OLM power successfully turned down");
}
