  • Method Details

    • setResumableCheck

      void setResumableCheck(Predicate<?> afterConsumeEval)
      This sets the predicate responsible for evaluating whether the processing can resume or not. Such predicate should return true if the consumption can resume, or false otherwise. The exact point of when the predicate is called is dependent on the component, and it may be called on either one of the available events. Implementations should not assume the predicate to be called at any specific point.
