Subject [Devicemap Wiki] Trivial Update of "Patterns2" by rezan
Date Tue, 13 Jan 2015 03:22:11 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Devicemap Wiki" for change notification.

The "Patterns2" page has been changed by rezan:
https://wiki.apache.org/devicemap/Patterns2?action=diff&rev1=27&rev2=28

  If no candidate patterns are found, the Default``Id is returned. If no
  Default``Id is defined, a null pattern is returned.
  
- It is valid for multpile patterns to share the same Pattern``Id. These patterns function
completely independent of each other.
+ 2 or more patterns may share the same Pattern``Id. These patterns function completely independent
of each other.
  
- 2 or more patterns cannot have identical Rank``Type, Rank``Value, and pattern tokens. This
results in undefined behavior when the patterns are candidates since they are identical. The
classifier is allowed to choose any one candidate in this situation, so the result can be
random.
+ 2 or more patterns cannot have identical Rank``Type, Rank``Value, and pattern tokens. This
results in undefined behavior when the patterns are candidates since they have identical rank.
The classifier is free to choose any one candidate in this situation.
  
  New pattern types and ranks can be introduced in the future. If a classifier encounters
a definition it cannot support, it must immediately return an initialization error.
