T - The type of the MessageMonitor created for every payload type.Must implement both MessageMonitor
and MetricSetpublic class PayloadTypeMessageMonitorWrapper<T extends MessageMonitor<Message<?>> & com.codahale.metrics.MetricSet> extends Object implements MessageMonitor<Message<?>>, com.codahale.metrics.MetricSet
MessageMonitor implementation which creates a new MessageMonitor for every Message payload type
ingested by it. The PayloadTypeMessageMonitorWrapper keeps track of all distinct payload types it has created
and only creates a new one if there is none present.
The type of MessageMonitor which is created for every payload type is configurable, as long as it implements
MessageMonitor and MetricSet.
