Method

byte[]getRedisKey(String keyPrefix, Xid xid)
get Redis Key 
byte[] prefix = keyPrefix.getBytes();
byte[] globalTransactionId = xid.getGlobalTransactionId();
byte[] branchQualifier = xid.getBranchQualifier();
byte[] key = new byte[prefix.length + globalTransactionId.length + branchQualifier.length];
System.arraycopy(prefix, 0, key, 0, prefix.length);
System.arraycopy(globalTransactionId, 0, key, prefix.length, globalTransactionId.length);
System.arraycopy(branchQualifier, 0, key, prefix.length + globalTransactionId.length,
        branchQualifier.length);

intgetXidSize(Xid xid)
The byte[]'s in Xid's are known to be 255 or less in length. 
byte[] gid = xid.getGlobalTransactionId();
byte[] bqual = xid.getBranchQualifier();
return INT_BYTES + 
        1 + 
        1 + 
        (gid == null ? 0 : gid.length) + 
        (bqual == null ? 0 : bqual.length);
booleansameTransaction(Xid x1, Xid x2)
Compares two Xid instances at the gtid level only.
