choose().option() switch case is not working for byte value

[Ajay Choudary]

Am using janusGraph-0.2.0

choose().option().option() chain is working with strings, integers & edge labels etc

But if choosen value is of type Byte.class, then always none option is executing.

Working query with Interger value:

> g.V().hasLabel("knowledge").has('views', 67).choose(values('views')).option(67, values('views')).option(none, constant('0'))

 67

Not working query with Byte value:

> g.V().hasLabel('knowledge').bothE('sharedTo').has('privilege', 2).choose(values('privilege')).option(2, values('privilege')).option(none, constant(0))

0

Any idea, how can i pass byte value to option.

This might be a problem with JanusGraph because I'm not seeing the problem on TinkerGraph:

gremlin> b = 1 as byte

==>1

gremlin> b.class

==>class java.lang.Byte

gremlin> g.V(1).property('b',b)

==>v[1]

gremlin> g.V(1).choose(values('b')).option(b, constant(true)).option(none,constant(false))

==>true

If that's not representative of your problem please let us know, but I think you might want to bring that up on the JanusGraph list (unless some JanusGraph heroes can help here).

This isn't specific to JanusGraph. The issue is the option comparison is using an integer rather than a byte. Continuing on Stephen's example:

gremlin> g.V(1).choose(values('b')).option(b, constant(true)).option(none,constant(false))
==>true

gremlin> g.V(1).choose(values('b')).option(1, constant(true)).option(none,constant(false))
==>false
gremlin> g.V(1).choose(values('b')).option(1 as byte, constant(true)).option(none,constant(false))
==>true

oh - sorry - i'm not smart.....stupid Java number comparisons......

Kuppitz should NumberHelper be used here?

Yea, we can do that (and we should). I guess this only requires a few minor changes in BranchStep.

Cheers,
