  • Method Details

    • getHandledClass

      Class<E> getHandledClass()
      Gets the exception class that this handles. This is necessary as method parameter type erasure occurs when classes are compiled without debugging information, and thus is lost when packaging applications in most cases.

      This method is called during environment construction.

      Returns:
      the handled class.
      Since:
      1.5.0
