DiffProvider for byte[]

[ghost]

Hi, I'm testing your library and found out that if a bean has byte[] it throws IllegalStateException. How can add a proper differ for this object type? I couldn't figure out a way of doing that reading your API. My differ will only base64 and compare the values to check whether has changed or not.

Thanks in advance.

sorry, duplicated.

Don't worry about it. Did the other issue give you enough pointers to solve your problem?

Yes it indeed did.

ObjectDifferBuilder.startBuilding().differs().register((differDispatcher, nodeQueryService) -> new ByteArrayDiffer()).build();

private static final class ByteArrayDiffer implements Differ {

@Override
public boolean accepts(Class<?> aClass) {
    return byte[].class.equals(aClass);
}

@Override
public DiffNode compare(DiffNode diffNode, Instances instances) {
    final DiffNode beanNode = new DiffNode(diffNode, instances.getSourceAccessor(), instances.getType());

    if(instances.areNull() || instances.areSame())
        beanNode.setState(DiffNode.State.UNTOUCHED);
    else if(instances.hasBeenAdded())
        beanNode.setState(DiffNode.State.ADDED);
    else if(instances.hasBeenRemoved())
        beanNode.setState(DiffNode.State.REMOVED);
    else
        beanNode.setState(DiffNode.State.CHANGED);

    return beanNode;
}

}

I just need to check whether it has changed so the code worked like a charm!

Thanks!
