Marko,
>> v.property(single,"name","marko")
But with multi-properties, would this not just mean add another single
value for name="marko"? We just established earlier in the conversation
that you can have multiple single-valued properties, and that these
multi-properties can even be the same value.
Thanks,
Mike
Hi,
If you are replacing a property its:
v.property("name").remove()
v.property("name","marko")
Or, check this (and this is the general answer to your question):
v.property(single,"name","marko")
There is Cardinality.single, Cardinality.set, and Cardinality.list.
Check out Features.getCardinality(String) too.
Get it?,

Yes. That is allowed.
Again, see Features.
You can do Features.supportsList(); (I forget the exact method).
Take care,
Marko.

Ok thanks Marko. But just to be clear - you could have a key with list
cardinality with multi-properties - that is to say, multiple lists, right?
Like for example, if the <V> in Vertex.property was a List? I assume this
would be quite an unusual case and I'm not sure why anyone would want to do
it, but it still needs to be supported?
Vertex v = ...
v.property(Cardinality.list, "prop", Arrays.asList("a", "b", "c"));
v.property(Cardinality.list, "prop", Arrays.asList("d", "e", "f"));

Hi Mike,
One more thing to add --- multi-properties are NOT lists. They are multiple properties of the same key. If you want a key->list[1,2,3] that is a value of list. That is also a Feature. I suspect you don't want that as that is typically not what is desired. You want:
name->marko
name->marko2
name->marko3
That is a "list" of multiple properties not a single property with value list :D
Get it?,
Marko.

If you want to replace "name", its single.
If you want to add a new "name," its list.
If you want to add a new "name" (repeats not allowed), its set.
Play with TinkerGraph and see:
gremlin> graph = TinkerGraph.open()
==>tinkergraph[vertices:0 edges:0]
gremlin> v = graph.addVertex()
==>v[0]
gremlin> v.property(single,'name','marko')
==>vp[name->marko]
gremlin> v.properties()
==>vp[name->marko]
gremlin> v.property(single,'name','marko2')
==>vp[name->marko2]
gremlin> v.properties()
==>vp[name->marko2]
gremlin> v.property(list,'name','marko')
==>vp[name->marko]
gremlin> v.properties()
==>vp[name->marko2]
==>vp[name->marko]
gremlin> v.property(list,'name','marko3')
==>vp[name->marko3]
gremlin> v.properties()
==>vp[name->marko2]
==>vp[name->marko]
==>vp[name->marko3]
gremlin> v.property(single,'name','marko4')
==>vp[name->marko4]
gremlin> v.properties()
==>vp[name->marko4]
gremlin> v.property(set,'name','marko5')
==>vp[name->marko5]
gremlin> v.properties()
==>vp[name->marko4]
==>vp[name->marko5]
gremlin> v.property(set,'name','marko5')
==>vp[name->marko5]
gremlin> v.properties()
==>vp[name->marko4]
==>vp[name->marko5]
