Package org.springframework.batch.repeat.interceptor

Class RepeatOperationsInterceptor

java.lang.Object
org.springframework.batch.repeat.interceptor.RepeatOperationsInterceptor
All Implemented Interfaces:
org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor
public class RepeatOperationsInterceptor extends Object implements org.aopalliance.intercept.MethodInterceptor
A MethodInterceptor that can be used to automatically repeat calls to a method on a service. The injected RepeatOperations is used to control the completion of the loop. Independent of the completion policy in the RepeatOperations the loop will repeat until the target method returns null or false. Be careful when injecting a bespoke RepeatOperations that the loop will actually terminate, because the default policy for a vanilla RepeatTemplate will never complete if the return type of the target method is void (the value returned is always not-null, representing the Void.TYPE).
