Re: [Hessianobjc-user] mapping BigDecimal to NSDecimalNumber

[Byron W. <by...@bl...>]

Hi Tore,

let me see your initWithCoder method and class interface. My  
BBSHessianMapDecoder class only implements the keyed archive methods.  
decodeValueOfObjCType:at: isn't a keyed archiver method of NSCoder.  
This is how I might implement my custom BigDecimalNumber custom class  
initWithCoder method:

@interface MyBigDecimalNumber: NSDecimalNumber <NSCoding> { }
...
...
...
- (id) initWithCoder : (NSCoder *) decoder {
	self = [[NSDecimalNumber alloc] initWithString:[decoder  
objectForKey:"value"]];
	return self;
}
... similar thing for encoding
