Package org.apache.camel.impl.debugger

Class BacklogDebugger

  • All Implemented Interfaces:
    AutoCloseable, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.StatefulService, org.apache.camel.SuspendableService
    public final class BacklogDebugger
extends org.apache.camel.support.service.ServiceSupport
    A Debugger that has easy debugging functionality which can be used from JMX with ManagedBacklogDebuggerMBean.

    This implementation allows setting breakpoints (with or without a condition) and inspect the Exchange dumped in XML in BacklogTracerEventMessage format. There is operations to resume suspended breakpoints to continue routing the Exchange. There is also step functionality, so you can single step a given Exchange.

    This implementation will only break the first Exchange that arrives to a breakpoint. If Camel routes using concurrency then sub-sequent Exchange will continue to be routed, if their breakpoint already holds a suspended Exchange.
