LogOrRethrowExceptionHandler (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.repeat.exception.LogOrRethrowExceptionHandler

All Implemented Interfaces:
ExceptionHandler
```
public class LogOrRethrowExceptionHandler
extends java.lang.Object
implements ExceptionHandler
```
Implementation of ExceptionHandler based on an Classifier. The classifier determines whether to log the exception or rethrow it. The keys in the classifier must be the same as the static enum in this class.

```
public void setExceptionClassifier(org.springframework.classify.Classifier<java.lang.Throwable,LogOrRethrowExceptionHandler.Level> exceptionClassifier)
```
    Setter for the Classifier used by this handler. The default is to map all throwable instances to LogOrRethrowExceptionHandler.Level.RETHROW.
    Parameters:
    exceptionClassifier - the ExceptionClassifier to use
  - handleException
```
public void handleException(RepeatContext context,
                            java.lang.Throwable throwable)
                     throws java.lang.Throwable
```
    Classify the throwables and decide whether to rethrow based on the result. The context is not used.
    Specified by:
    handleException in interface ExceptionHandler
    Parameters:
    context - the current RepeatContext. Can be used to store state (via attributes), for example to count the number of occurrences of a particular exception type and implement a threshold policy.
    throwable - an exception.
    Throws:
    java.lang.Throwable - thrown if exceptionClassifier is classified as LogOrRethrowExceptionHandler.Level.RETHROW.
