Class DefaultManagementStrategy

java.lang.Object

org.apache.camel.support.ServiceSupport

org.apache.camel.management.DefaultManagementStrategy

All Implemented Interfaces:

CamelContextAware, Service, ShutdownableService, ManagementStrategy, StatefulService, SuspendableService

Direct Known Subclasses:

ManagedManagementStrategy

public class DefaultManagementStrategy
extends ServiceSupport
implements ManagementStrategy, CamelContextAware

A default management strategy that does not manage.

This is default only used if Camel detects that it cannot use the JMX capable ManagedManagementStrategy strategy. Then Camel will fallback to use this instead that is basically a simple and noop strategy.

This class can also be used to extend your custom management implement. In fact the JMX capable provided by Camel extends this class as well.
