Enum Class SurroundingTransactionDetectorMethodInterceptor

java.lang.Object

java.lang.Enum<SurroundingTransactionDetectorMethodInterceptor>

org.springframework.data.repository.core.support.SurroundingTransactionDetectorMethodInterceptor

All Implemented Interfaces:

Serializable, Comparable<SurroundingTransactionDetectorMethodInterceptor>, Constable, Advice, Interceptor, MethodInterceptor

public enum SurroundingTransactionDetectorMethodInterceptor
extends Enum<SurroundingTransactionDetectorMethodInterceptor>
implements MethodInterceptor

MethodInterceptor detecting whether a transaction is already running and exposing that fact via isSurroundingTransactionActive(). Useful in case subsequent interceptors might create transactions themselves but downstream components have to find out whether there was one running before the call entered the proxy.
