Re: creating a vertex with a LIST property in a single gremlin statement

It is supported syntax. It's part of the TinkerPop API.  0.1.0 and 0.1.1 both have the same version of TinkerPop Gremlin.

Hi All,

(first entry, so please be patient)

Following is more of a gremlin question.  I have a JG schema with a property called status, cardinality list.

status = mgmt.makePropertyKey('status').dataType(String.class).cardinality(Cardinality.LIST).make();

In documentation it has been suggested to do this:

myVertex = graph.addVertex(label,'myVertex')
myVertex.property('status', 'HI')
myVertex.property('status', 'BYE')

which of course it works as advertised.  However, I found that the following shorthand will also work in JanusGraph 0.1.1 (but not in 0.1.0)

graph.addVertex(label,'myVertex', 'status', 'HI', 'status', 'BYE')

Can someone help explain if this is a supported syntax, or simply some syntactic sugar.  Also, I cannot find any documentation on the key differences between JanusGraph 0.1.0 and 0.1.1 with respect to gremlin.

$ echo $CASSANDRA_HOME
/path/janusgraph/apache-cassandra-2.1.17
$ which janusgraph.sh
/path/janusgraph/janusgraph-0.1.1-hadoop2/bin/janusgraph.sh
$ which gremlin.sh
/path/janusgraph/janusgraph-0.1.1-hadoop2/bin/gremlin.sh

Thank you,

Peter
