ReedSolomonDecoder

java.lang.Object
- com.google.zxing.common.reedsolomon.ReedSolomonDecoder

```
public final class ReedSolomonDecoder
extends java.lang.Object
```
Implements Reed-Solomon decoding, as the name implies.

The algorithm will not be explained here, but the following references were helpful in creating this implementation:
- Bruce Maggs. "Decoding Reed-Solomon Codes" (see discussion of Forney's Formula)
- J.I. Hall. "Chapter 5. Generalized Reed-Solomon Codes" (see discussion of Euclidean algorithm)
Much credit is due to William Rucklidge since portions of this code are an indirect port of his C++ Reed-Solomon implementation.

- Method Detail
  - decode
```
public void decode(int[] received,
                   int twoS)
            throws ReedSolomonException
```
    Decodes given set of received codewords, which include both data and error-correction codewords. Really, this means it uses Reed-Solomon to detect and correct errors, in-place, in the input.
    
    Parameters:
    
    received - data and error-correction codewords
    
    twoS - number of error-correction codewords available
    
    Throws:
    
    ReedSolomonException - if decoding fails for any reason
