## Detailed Description

general exception of the basic_json class

This class is an extension of `std::exception` objects with a member id for exception ids. It is used as the base class for all exceptions thrown by the basic_json class. This class can hence be used as "wildcard" to catch exceptions.

Subclasses:

- parse_error for exceptions indicating a parse error
- invalid_iterator for exceptions indicating errors with iterators
- type_error for exceptions indicating executing a member function with a wrong type
- out_of_range for exceptions indicating access out of the defined range
- other_error for exceptions indicating other library errors

@liveexample{The following code shows how arbitrary library exceptions can be caught.,exception}
