Agreed. Still I think it should be possible to cast the value one
time in the enum and not every time I use the enum.
Hmm, doesn't seem to me that it is still an enum then. You're
counting on these enums having particular integer values; so you
should simply be using integer constants instead of enums. Enums,
properly used, don't even need to HAVE any integer values -- they're
just unique, opaque identifiers within a set.
Well, perhaps I need to write how I use the enums here...
From "Apple Filing Protocol Programming Guide":"Apple Filing Protocol
Data Types":"Directory Bitmap":
enum {
kFPAttributeBit = 0x1,
kFPParentDirIDBit = 0x2,
kFPCreateDateBit = 0x4,
kFPModDateBit = 0x8,
kFPBackupDateBit = 0x10,
kFPFinderInfoBit = 0x20,
kFPLongNameBit = 0x40,
kFPShortNameBit = 0x80,
kFPNodeIDBit = 0x100,
kFPOffspringCountBit = 0x0200,
kFPOwnerIDBit = 0x0400,
kFPGroupIDBit = 0x0800,
kFPAccessRightsBit = 0x1000,
kFPProDOSInfoBit = 0x2000 // AFP version 2.2 and earlier
kFPUTF8NameBit = 0x2000, // AFP version 3.0 and later
kFPUnixPrivsBit = 0x8000 // AFP version 3.0 and later
};
So I want to use these constants in code. To have no huge "k..." name
space I have a Module where I want to use enums via "public access".
So I want to call here e.g. MyModule.DirectoryBitmapConstants.kFPLongNameBit
When I want to use this in the Bitwise operator I need to cast.
I think the usage as shown above should be supported without casting.
Comments please.
Cheers,
Tom
