Class PayloadTypeMessageMonitorWrapper<T extends org.axonframework.monitoring.MessageMonitor<org.axonframework.messaging.Message<?>> & com.codahale.metrics.MetricSet>

java.lang.Object

org.axonframework.metrics.PayloadTypeMessageMonitorWrapper<T>

Type Parameters:

T - The type of the MessageMonitor created for every payload type.Must implement both MessageMonitor and MetricSet

All Implemented Interfaces:

com.codahale.metrics.Metric, com.codahale.metrics.MetricSet, org.axonframework.monitoring.MessageMonitor<org.axonframework.messaging.Message<?>>

public class PayloadTypeMessageMonitorWrapper<T extends org.axonframework.monitoring.MessageMonitor<org.axonframework.messaging.Message<?>> & com.codahale.metrics.MetricSet>
extends Object
implements org.axonframework.monitoring.MessageMonitor<org.axonframework.messaging.Message<?>>, com.codahale.metrics.MetricSet

A 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.
