Re: [Hessianobjc-user] Fwd: Which hessian jar to use?

[Tom D. <tgd...@gm...>]

Here's a barely-tested fix which seems to work for me -- I haven't set  
SVN up yet, so it isn't a patch...

- (NSString *) decodeStringChunk {
     int len = [self decodeStringLength];
     if(len == 0) {
         return @"";
     }
     //alloc enough memory for the string +1 for null terminator
	// this may be twice the number of characters + 1 for a pathological
	// case where each character is a two byte character in UTF-8
     uint8_t * readData = malloc((2*len+1) * sizeof(uint8_t));
     if(readData == NULL) {
        NSLog(@"failed to alloc memory for string with len =%i",len);
        return @"";
     }
     //set all to null.
     memset(readData,0,2*len+1);
	// we need to read at least 'len' bytes, but then need to check if we  
need
	// to read more
     [dataInputStream read:readData maxLength:len];
	int totalLength = len;
	int multiByteCharsFound = 0;
	while ([self countUTFChars:readData length:totalLength  
found:&multiByteCharsFound] < len)
	{
		[dataInputStream read:(readData + totalLength)  
maxLength:multiByteCharsFound - (len - totalLength)];
		totalLength += multiByteCharsFound - (len - totalLength);
	}
     NSString * retString = [NSString stringWithUTF8String:(const char  
*)readData] ;
     free(readData);
     return retString;
}

- (int) countUTFChars:(uint8_t*)data length:(int)length found: 
(int*)foundp {
	*foundp = 0;
	int i;
	int count = 0;
	for (i = 0; i < length; ++i)
	{
		++count;
		if (data[i] > 0x7f)
		{
			int extra = 1;
			if (data[i] > 0xdf)
			{
				extra = 2;
				if (data[i] > 0xef)
				{
					extra = 3;
				}
			}
			*foundp += extra;
			i += extra;
		}
	}
	return count;
}
