◆ getImpliedARCOwnership()

getImpliedARCOwnership - Given a set of property attributes and a type, infer an expected lifetime.

The type's ownership qualification is not considered.

Returns OCL_None if the attributes as stated do not imply an ownership. Never returns OCL_Autoreleasing.

◆ SelectPropertyForSynthesisFromProtocols()

SelectPropertyForSynthesisFromProtocols - Finds the most appropriate property declaration that should be synthesised in all of the inherited protocols.

It also diagnoses properties declared in inherited protocols with mismatched types or attributes, since any of them can be candidate for synthesis.
