Interface WorkerInterceptor

  • All Known Implementing Classes:
    WorkerInterceptorBase
    public interface WorkerInterceptor
    Intercepts workflow and activity executions.

    Prefer extending WorkerInterceptorBase and overriding only the methods you need instead of implementing this interface directly. WorkerInterceptorBase provides correct default implementations to all the methods of this interface.

    You may want to start your implementation with this initial structure: 

    
 public class CustomWorkerInterceptor extends WorkerInterceptorBase {
   // remove if you don't need to have a custom WorkflowInboundCallsInterceptor or
   // WorkflowOutboundCallsInterceptor
  @Override
   public WorkflowInboundCallsInterceptor interceptWorkflow(WorkflowInboundCallsInterceptor next) {
     return new CustomWorkflowInboundCallsInterceptor(next) {
       // remove if you don't need to have a custom WorkflowOutboundCallsInterceptor
       @Override
       public void init(WorkflowOutboundCallsInterceptor outboundCalls) {
         next.init(new CustomWorkflowOutboundCallsInterceptor(outboundCalls));
       }
     };
   }

   // remove if you don't need to have a custom ActivityInboundCallsInterceptor
  @Override
   public ActivityInboundCallsInterceptor interceptActivity(ActivityInboundCallsInterceptor next) {
     return new CustomActivityInboundCallsInterceptor(next);
   }

   private static class CustomWorkflowInboundCallsInterceptor
       extends WorkflowInboundCallsInterceptorBase {
     public CustomWorkflowInboundCallsInterceptor(WorkflowInboundCallsInterceptor next) {
       super(next);
     }

     // override only the methods you need
   }

   private static class CustomWorkflowOutboundCallsInterceptor
       extends WorkflowOutboundCallsInterceptorBase {
     public CustomWorkflowOutboundCallsInterceptor(WorkflowOutboundCallsInterceptor next) {
       super(next);
     }

     // override only the methods you need
   }

   private static class CustomActivityInboundCallsInterceptor
       extends ActivityInboundCallsInterceptorBase {
     public CustomActivityInboundCallsInterceptor(ActivityInboundCallsInterceptor next) {
       super(next);
     }

     // override only the methods you need
   }
 }
