Subject: Add and use a method for querying whether a property is revisioned.
X-Git-Tag: qt-v5.0.0-alpha1~285
X-Git-Url: http://review.tizen.org/git/?p=profile%2Fivi%2Fqtdeclarative.git;a=commitdiff_plain;h=ab727e6702e949c8f36649f16a81780746ebb2de

Add and use a method for querying whether a property is revisioned.

Accessor data and the revision are now unioned, so querying
the value directly can give incorrect results.
