is it right that FontData owns the FontPlatformData it gets assigned?
And that FontData::platformInit and ::platformDestroy define the
lifetime of the FontDataPlatform. So if I destroy the "platform
specific objects" created by FontPlatformData I will not interact
badly with the cache? This ownerhip in the Gdk port was wrong and I
needed some time to figure that out.
While reading the code I think I have found a oversight in the
FontPlatformData of the Mac port. The FontCache uses a HashMap. This
HashMap will use the (implicit) Copy-Constructor and the (implicit)
Assignment-Operator of the FontPlatformData to store objects in the
I'm not that familiar with CoreFoundations reference counting, but
CFRetain is called in the explicit Copy-Constructor for the NSFont*
and I wonder why there isn't an explicit assignment operator
increasing the reference on the other font and decreasing it on the
Why does this implicit copy operator work here?
Comments would be appreciated.
