[xmlvm-users] NSData Bug

[Tim C. <ti...@vi...>]

Hi,

I am trying to consume a JSON response, however, NSData byte array size is only 26. I saw there was an earlier discussion about this, but no resolution.

When reviewing the code I see this logic:

	do {
                byte[] buf = new byte[READ_BUF_SIZE];
                i = in.read(buf);

                if (i > 0) {
                    l.add(buf);
                    bytesRead += i;
                }
                
            } while (i == READ_BUF_SIZE);

How is it possible that (i == READ_BUF_SIZE)? In other words read the input stream while i = 32767 - this will end after the first try. I can see that my InputStream does contain all of the data but the readData method only returns a 26 character portion.

I am fixing this for my own immediate needs but in the meantime I wanted to understand if I was missing something since I would assume this to be a fundamental need for a lot of apps???

Here is my fix for the time being:

private void readData(InputStream in) {
        data = new byte[READ_BUF_SIZE];
        
        try {
            int offset = 0;
            int numRead = 0;
            
            while (offset < data.length && (numRead=in.read(data, offset, data.length-offset)) >= 0)
                {
                offset += numRead;
                }

            in.close();
        } catch (IOException ex) {
            // Do nothing
        }
    }
