hicpp-exception-baseclass
|

|
|
=========================
|

|
|
|
||
|
|
Ensure that every value that in a ``throw`` expression is an instance of
|
||
|
|
``std::exception``.
|
||
|
|
|
||
|
|
This enforces `rule 15.1 <http://www.codingstandard.com/section/15-1-throwing-an-exception/>`_
|
||
|
|
of the High Integrity C++ Coding Standard.
