TryCatchHandler class

An Handler wrapper which calls the wrapped handler and does the following:

  • when an instance of Response is returned or thrown by the wrapped handler, the response is returned
  • when another error is thrown by the wrapped handler and the onError callback is set, the error will be converted to a response
  • otherwise the error will be rethrown.
