question: public boolean isParityCorrect ( byte [ ] [ ] shards , int firstByte , int byteCount ) { checkBuffersAndSizes ( shards , firstByte , byteCount ) ; byte [ ] [ ] toCheck = new byte [ parityShardCount ] [ ] ; System . arraycopy ( shards , dataShardCount , toCheck , 0 , parityShardCount ) ; return codingLoop . checkSomeShards ( parityRows , shards , dataShardCount , toCheck , parityShardCount , firstByte , byteCount , null ) ; }
target:  Returns true if the parity shards contain the right data.
