Examples of OGraphVertex

com.orientechnologies.orient.core.db.graph.OGraphVertex
GraphDB Vertex class. It represent the vertex (or node) in the graph. The Vertex can have custom properties. You can read/write them using respectively get/set methods. The Vertex can be connected to other Vertexes using edges. The Vertex keeps the edges separated: "inEdges" for the incoming edges and "outEdges" for the outgoing edges. @see OGraphEdge
