A problem is created by diagnostics to signal a failure or some inefficiency. Exceptionally it can also be created by repairs that do not trigger on problems. A problem is also a blackboard so that it can store extra data. The issued-by slot is automatically set by method handle-diagnosed-problems. The fixes slot is automatically set to the return value of repair-object and repair-problem
| :issued-by | [Initarg] |
| :fixes | [Initarg] |
| issued-by | [Slot] |
The object that created this problem, i.e. the diagnostic.
| fixes | [Slot] |
fixes of this problem
Base class for diagnostics.
| :trigger | [Initarg] |
| trigger | [Slot] |
A trigger specifies to which notification the diagnostic should respond. It can be a single symbol or a (nested) list of symbols. It is also possible to use a variable (a symbol starting with ?) which can match to any symbol or list. A trigger should respond to at least one notification somewhere, otherwise the diagnostic will never run
Base class for a repair.
| :trigger | [Initarg] |
| :score | [Initarg] |
| trigger | [Slot] |
A trigger specifies to which notification the repair responds. It can be a single symbol or a (nested) list of symbols. It is also possible to use a variable (a symbol starting with ?) which can match to any symbol or list. Normally a trigger should respond to at least one notification somewhere.
Fixes are created by repairs
| :repair :issued-by | [Initarg] |
| :problem | [Initarg] |
| :restart-data | [Initarg] |
| issued-by | [Slot] |
pointer to the repair
| problem | [Slot] |
pointer to the repaired problem
| restart-data | [Slot] |
restart and with what data (can be t also)
Returns and (with setf) changes the restart-data of the specified fix
overload for allowing to restart an object
