    • setErrorHandler

      public void setErrorHandler(ErrorHandler handler)
      Allow an application to register an error event handler.

      If the application does not register an error event handler, all error events reported by the parser will cause an exception to be thrown.

      Applications may register a new or different handler in the middle of a parse, and the parser must begin using the new handler immediately.

      Specified by:
      setErrorHandler in interface Parser
      Parameters:
      handler - The error handler.
