      • setExceptionClassifier

        public void setExceptionClassifier​(org.springframework.classify.SubclassClassifier<java.lang.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​(java.util.Map<java.lang.Class<? extends java.lang.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​(java.lang.Throwable t,
                          int 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
