BEFORE_CONNECTION_HANDLER

public static final String BEFORE_CONNECTION_HANDLER

Exchange specific parameter is used for providing Runnable action which is caused before setup new connection. For example adding throttle control for limiting too often opening connections:

 static final TimedSemaphore limiter = new TimedSemaphore(1, MINUTES, 15);
 ExchangeSpecification spec = exchange.getDefaultExchangeSpecification();
 spec.setExchangeSpecificParameters(ImmutableMap.of(
   {@link ConnectableService#BEFORE_CONNECTION_HANDLER}, () -> limiter.acquire()
 ));
