You can use the nonpersistence (n) qualifier for objects and attributes. It's very useful for attributes that may not be valid across a system restart and don't need to be saved.
The table below describes the effects of the nonpersistence qualifier on PPS objects and attributes:
| Syntax | Action | Object | Attribute |
|---|---|---|---|
| n | Set | Make the object and its attributes nonpersistent; ignore any persistence qualifiers set on this object's attributes. | Make the attribute nonpersistent. |
| -n | Clear | Make the object persistent; persistence of the object's attributes is determined by each attribute's qualifiers. | Make the attribute persistent, if the attribute's object is also persistent. |
Setting the nonpersistence qualifier on an object overrides any nonpersistence qualifiers set on the object's attributes and is therefore convenient if you need to make a temporary object in which nothing persists.
