Task Action: Add

The add action allows to add a unidirectional relation from node(s) in the result to node(s) stored in a variable.

This action should only be used after a task returning node(s) as result.

The use of add doesn't impact the current result.

Therefore, we could modify the running example to add a relation from sensors nodes to rooms nodes:

    .setProperty("name", Type.STRING, "room_{{i}}")
    .indexNode("rooms", "name")
        .setProperty("sensor", Type.STRING, "sensor_{{i}}")
        .addTo("sensors", "parentRoom")
        .add("room","parentRoom") //Change here !!!
).execute(g, null);

The opposite operation (from variable node(s) to result node(s)) can be done using the addTo task.

Similar to setProperty, when several nodes are present in the result, the add task is applied to all of them.

If the relation wasn't existing before, a new one is created, otherwise node(s) are just added to the relation.
