This class should not be used directly but through macro TYPEDEF_ERR_INFO. It is derived from boost::error_info<tag, type> and similarly as its parent it is tailored for passing a value of type Type
from the throw point to the catch point. Compared to boost::error_info it provides manipulators val
and qval
which can by used in formating exception message to the ExcStream. The first manipulator evaluates directly to the output of the stored value, while qval
puts the output into single quotas.
The static function ref
can be used when you want to extract and output some particular information from the passed value. However, if no value is given at throw point this function simply aborts. There is probably no way how to make the check and still keep flexibility in manipulation with the result of ref
function.
For usage see documentation of TYPEDEF_ERR_INFO

Stream manipulator used to output the stored value. We have to use special stream ExcStream, that has overloaded << operator in order to support manipulators 'val' and 'qval'.
