Status of inactive property


flag = isInactivePropertyImpl(obj,prop)


flag = isInactivePropertyImpl(obj,prop) specifies whether a public, non-state property is inactive and not visible for the current object configuration. An inactive property is a property that is not relevant to the object because of the values of other properties. Inactive properties are not shown if you use the disp method to display object properties. If you attempt to use public access to directly access or use get or set on an inactive property, a warning occurs.

Run-Time Details

isInactiveProperty is called by disp, get and set methods.
