AbstractExceptionDiagnoser<E extends Exception> class abstract

Base class for creating typed exception diagnosers that target a specific exception type E.

This abstract diagnoser:

• Filters the exception chain to find a cause of type E
• Delegates actual diagnosis to the subclass via doDiagnose
• Implements ExceptionDiagnoser and ClassGettable for type reflection

Subclasses must implement doDiagnose to provide meaningful `ExceptionDiagnosis` for the matched exception type.

Example

class FormatExceptionDiagnoser extends AbstractExceptionDiagnoser<FormatException> {
  @override
  ExceptionDiagnosis? doDiagnose(Exception exception, FormatException cause) {
    return ExceptionDiagnosis(
      cause: cause,
      description: "Invalid format encountered",
      action: "Check input data or configuration",
    );
  }
}
