How Do I Perform Pagination with TinkerPop in Java?

In Gremlin, we can paginate like this:

gremlin> g.V().hasLabel('person').fold().as('persons','count').
               select('persons','count').
                 by(range(local, 0, 2)).
                 by(count(local))
==>[persons:[v[1],v[2]],count:4]

I'm trying to do the same thing in Java, but have no idea what local is in this case. My current query looks like this:

.fold()
.as("persons", "count")
.select("persons", "count")
.by(__.range(0, 2))
.by(__.count())

However, it always returns all results with a count of 1. How would the pagination be correctly performed in Java?

The details for pagination are described best here but your question seems like it's more about use of local. local is an value from the enum Scope and a common import for all languages Gremlin is implemented in.

import static org.apache.tinkerpop.gremlin.process.traversal.Scope.local;

You can always find out more about the arguments to Gremlin steps by looking at the javadoc.
