Subject: Conformant implementation of the object internal methods
X-Git-Tag: upstream/5.2.1~669^2~659^2~884
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ddba8f6bb06f0f2312a8c070f8cf4a9e079c9ca7;p=platform%2Fupstream%2Fqtdeclarative.git

Conformant implementation of the object internal methods

See section 8.12 of the standard. This implements
8.12.1 - 8.12.7 and 8.12.9

Also gave these methods standard conformant names.
They are marked as [[foo]] in the standard, which
translates to __foo__ in our code.
