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.
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.- Author:
