Description Jaroslav Tulach 2016-02-22 05:04:40 UTC 
Let's introduce

 @Property(mutable=false)

to define semi-immutable property that can only be changed in construction time before the object is passed to underlaying Technology. Attempts to modify the object then yield IllegalStateException. Technologies may decide to represent such non-mutable property in more effective way - for example Knockout will use plain JavaScript values (number, string, array, boolean) rather than observables.

Please review the changes in the @Property and its processor:

The change for ko4j module is here:
http://source.apidesign.org/hg/html~html4j/rev/c61d247f087a

Now we are missing just a note in overview.html and some real world sample in Javadoc.

Documentation overview fixed:
