Detailed Description
Interface for Kernel error handler implementation
This manager is reponsible for handling errors in the framework. Errors in the framework are considered as not acceptable behavior that can be detected and handled by the system. The concept of error is thus independant of warning or fatal crashes that must be handled separately.

Member Function Documentation
|
pure virtual |
Push error to the manager.
- Parameters
-
type the error type description a self-explanatory description message
Errors already added to the manager will be nested in the newly added error.
|
pure virtual |
Push error with location information to the manager.
- Parameters
-
type the error type description a self-explanatory description of the error filename the source file where the error was detected line the line number where the error was detected
Errors already added to the manager will be nested in the newly added error.
|
pure virtual |
Release manager errors.
Release last error added to the manager and potentially all the nested errors recursively.
- Warning
- After this call, do not use pointers to IError retrieved before. It will lead to unexpected behavior mostly due to dangling pointers.
|
pure virtual |
Check for existing errors in the manager.
- Returns
- true if manager contains errors, false otherwise
|
pure virtual |
Get last error added to the manager.
- Returns
- the error if manager contains errors, nullptr otherwise
- Warning
- The manager keeps the ownership of IError instances. Therefore the API consumer is not responsible for their life cycle/management and must use releaseErrors to release them.
|
pure virtual |
Get description of last error added to the manager.
- Returns
- the description if manager contains errors, empty string otherwise
|
pure virtual |
Get type of last error added to the manager.
- Returns
- the type if manager contains error, NoErrorFound otherwise
