Ivan Mushketyk commented on FLINK-4440:
---------------------------------------
I assume that it will be used for instantiating in test cases, and in library
code as well. For example Graph class contains the following code:
{code:java}
out.collect(new Vertex<K, NullValue>(edge.f0, NullValue.getInstance()));
out.collect(new Vertex<K, NullValue>(edge.f1, NullValue.getInstance()));
{code}
which can be rewritten as:
{code:java}
out.collect(Vertex.create(edge.f0));
out.collect(Vertex.create(edge.f1));
{code}
and this is not the only example.

> Project: Flink
> Issue Type: Improvement
> Components: Gelly
> Reporter: Ivan Mushketyk
> Assignee: Ivan Mushketyk
> Priority: Trivial

> It would be better if one could create vertex/edges like this:
> {code:java}
> Vertex<Integer, NullValue> v = Vertex.create(42);
> Edge<Integer, Integer, NullValue> e = Edge.create(5, 6);
> {code}
> Instead of this:
> {code:java}
> Vertex<Integer, NullValue> v = new Vertex<Integer, NullValue>(42,
> NullValue.getInstance());
> Edge<Integer, Integer, NullValue> e = new Edge<Integer, Integer,
> NullValue>(5, 6, NullValue.getInstance());
> {code}
