Class MetricsHelper

java.lang.Object

com.amazonaws.services.kinesis.metrics.impl.MetricsHelper

public class MetricsHelper
extends java.lang.Object

MetricsHelper assists with common metrics operations, most notably the storage of IMetricsScopes objects in a ThreadLocal so we don't have to pass one throughout the whole call stack.
