It is common for a setting to have a default value that is calculated somehow—for example, it is inherited from the parent object. If a custom value is not specified, then the default value is used. Since the default value is calculated, it can cause the effective value to change. For example, if the default is inherited from a parent object, then the effective value may change because the parent was changed. By contrast, if a custom value has been assigned, then these external influences will not occur, even if the custom value happens to be the same string as the default value. The object manages three pieces of information: the current value, a read-only default value, and a Boolean state that indicates whether the default is being used.
For example, the FriendlyUrlSegment property is represented as a CustomizableString object for which a default value is generated from the name of the underlying Term object is automatically reflected as changes to the generated URL segment. If a custom URL segment is not explicitly assigned, then changes to the name of the Term object will be reflected automatically as changes to the generated URL segment.
