Reuse normalizer in ND4J/DL4J

I wonder what's the proper way to reuse a normalizer in ND4J/DL4J. Currently, I save it follows:

final DataNormalization normalizer = new NormalizerStandardize();
normalizer.fit( trainingData );
normalizer.transform( trainingData );
normalizer.transform( testData );

try {
    final NormalizerSerializer normalizerSerializer = new NormalizerSerializer();
    normalizerSerializer.addStrategy( new StandardizeSerializerStrategy() );
    normalizerSerializer.write( normalizer, path );
} catch ( final IOException e ) {
    // ...
}

And load it via:

try {
    final NormalizerSerializer normalizerSerializer = new NormalizerSerializer();
    normalizerSerializer.addStrategy( new StandardizeSerializerStrategy() );
    final DataNormalization normalizer = normalizerSerializer.restore( path );
} catch ( final Exception e ) { // Throws Exception instead of IOException.
    // ...
}

Is that OK? Unfortunately, I wasn't able to find more information in the docs.
