Detailed Description

This is a base class for exceptions thrown from the DNS library module.

Normally, the exceptions are thrown via a convenient shortcut macro, isc_throw, which automatically gives trivial parameters for the exception such as the file name and line number where the exception is triggered.

what() [1/2]

const char * isc::Exception::what ( ) const throw (  )

Returns a C-style character string of the cause of the exception.

Note: we normally don't use exception specifications, but this is an "exception" to that policy as it's enforced by the base class.

Here is the call graph for this function:

what() [2/2]

const char * isc::Exception::what ( bool verbose ) const throw (  )

virtual

Returns a C-style character string of the cause of exception.

With verbose set to true, also returns file name and line numbers. Note that we can't simply define a single what() method with parameters, as the compiler would complain that it shadows the base class method.

Parameters

verbose

if set to true, filename and line number will be added.

Returns

A C-style character string of the exception cause.
