    • setExceptionClassifier

      public void setExceptionClassifier(org.springframework.classify.SubclassClassifier<Throwable,SkipPolicy> classifier)
      The classifier that will be used to choose a delegate policy.
      Parameters:
      classifier - the classifier to use to choose a delegate policy

    • setPolicyMap

      public void setPolicyMap(Map<Class<? extends Throwable>,SkipPolicy> policyMap)
      Setter for policy map. This property should not be changed dynamically - set it once, e.g. in configuration, and then don't change it during a running application. Either this property or the exception classifier directly should be set, but not both.
      Parameters:
      policyMap - a map of String to SkipPolicy that will be used to create a Classifier to locate a policy.

    • shouldSkip

      public boolean shouldSkip(Throwable t, long skipCount) throws SkipLimitExceededException
      Consult the classifier and find a delegate policy, and then use that to determine the outcome.
      Specified by:
      shouldSkip in interface SkipPolicy
      Parameters:
      t - the throwable to consider
      skipCount - the current skip count
      Returns:
      true if the exception can be skipped
      Throws:
      SkipLimitExceededException - if a limit is exceeded
