How to create an adjacency between two vertices with an edge label creation

Synopsis

connection('outV', 'inV')

Description

An adjacency between two vertices is created using an edge label and the vertex labels of the outgoing and incoming vertices. This step is used in conjunction with edgeLabel().

Examples

Create an edge label isA specifying that the outgoing vertex label is ingredient and the incoming vertex label is FridgeItem.
schema.edgeLabel('isA').connection('ingredient', 'FridgeItem).create()
An adjacency between the vertexLabel author and author specifying the edgeLabel knows.
schema.edgeLabel('knows').connection('author', 'author').add()
