Logging NSData

[Andreas Höschler]

Hi all,

I am logging out NSDictionaries that sometimes contain NSData instances as 
values. On MacOSX NSData::description is called to determine a string that is 
used in the output. I don't want to see tons of hex values for large NSData 
objects in the output and therefore wrote the following category:

@implementation NSData (SRDataExtension)

- (NSString *)description
{
   return [NSString stringWithFormat:@"<data of length %d>", [self length]];
}

@end

This works great on MacOSX but not under GNUstep. It seems that description is 
not called under GNUstep when a dictionary is logged out with

        NSLog(@"dic %@", dic);

Any idea?

Thanks a lot!
