Nonpersistence qualifier

The nonpersistence qualifier can be used for objects and attributes. It's very useful on 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 the individual 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.
