Examples of org.apache.thrift.TSerializer

org.apache.thrift.TSerializer
Generic utility for easily serializing objects into a byte array or Java String.

  public static String asBase64String(TCredentials cred) throws AccumuloSecurityException {
    return new String(Base64.encodeBase64(asByteArray(cred)), Charset.forName("UTF-8"));
  }
  
  public static byte[] asByteArray(TCredentials cred) throws AccumuloSecurityException {
    TSerializer ts = new TSerializer();
    try {
      return ts.serialize(cred);
    } catch (TException e) {
      // This really shouldn't happen
      log.error(e, e);
      throw new AccumuloSecurityException(cred.getPrincipal(), SecurityErrorCode.SERIALIZATION_ERROR);
