Package org.springframework.batch.repeat.exception

Interface ExceptionHandler

All Known Implementing Classes:
CompositeExceptionHandler, DefaultExceptionHandler, LogOrRethrowExceptionHandler, RethrowOnThresholdExceptionHandler, SimpleLimitExceptionHandler, SimpleRetryExceptionHandler
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface ExceptionHandler
Handler to allow strategies for re-throwing exceptions. Normally a CompletionPolicy will be used to decide whether to end a batch when there is no exception, and the ExceptionHandler is used to signal an abnormal ending - an abnormal ending would result in an ExceptionHandler throwing an exception. The caller will catch and re-throw it if necessary.
