Detailed Description

this is the parent class of all exception classes.

this is a pure virtual class that provide some simple mechanisme to carry the information about the cause of the exception, as well as some a complex mechanim which not used often in libdar that keep trace, for each exception throwing process, of the different calls by which the current exception has been exiting.

Member Function Documentation

void libdar::Egeneric::dump ( ) const

dump all information of the exception to the standard error

Note
deprecated call, replaced by dump_str()
const std::string& libdar::Egeneric::find_object ( const std::string &  location) const

retrieve the objet (object) associated to a given "lieu" (location) from the stack

Parameters
[in]locationkey to look for the value of
Returns
returns an empty string if key is not found in the stack
const std::string& libdar::Egeneric::get_message ( ) const
inline

get the message explaing the nature of the exception

This is probably the only method you will use for all the the exception, as you will not have to create such objects and will only need to get the error message thanks to this method
