Enumeration Type Documentation

MangledEncoding

enum MangledEncoding

Enumerator
Empty	If the Mangled object has neither a mangled name or demangled name we can encode the object with one zero byte using the Empty enumeration.
DemangledOnly	If the Mangled object has only a demangled name and no mangled named, we can encode only the demangled name.
MangledOnly	If the mangle name can calculate the demangled name (it is the mangled/demangled counterpart), then we only need to encode the mangled name as the demangled name can be recomputed.
MangledAndDemangled	If we have a Mangled object with two different names that are not related then we need to save both strings. This can happen if we have a name that isn't a true mangled name, but we want to be able to lookup a symbol by name and type in the symbol table. We do this for Objective C symbols like "OBJC_CLASS_$_NSValue" where the mangled named will be set to "OBJC_CLASS_$_NSValue" and the demangled name will be manually set to "NSValue". If we tried to demangled the name "OBJC_CLASS_$_NSValue" it would fail, but in these cases we want these unrelated names to be preserved.
