java.lang.Object
- org.axonframework.eventhandling.AbstractEventProcessor.Builder
- - org.axonframework.eventhandling.SubscribingEventProcessor.Builder

Enclosing class:

SubscribingEventProcessor
```
public static class SubscribingEventProcessor.Builder
extends AbstractEventProcessor.Builder
```
Builder class to instantiate a SubscribingEventProcessor.
The RollbackConfigurationType defaults to a RollbackConfigurationType.ANY_THROWABLE, the ErrorHandler is defaulted to a PropagatingErrorHandler, the MessageMonitor defaults to a SpanFactory is defaulted to a NoOpSpanFactory, the MessageMonitor defaults to a NoOpMessageMonitor, the EventProcessingStrategy defaults to a DirectEventProcessingStrategy and the TransactionManager defaults to the NoTransactionManager.INSTANCE. The Event Processor name, EventHandlerInvoker and SubscribableMessageSource are hard requirements and as such should be provided.
