public PropertyGraph.Vertex<ID> connectsTo(ID target)

Description copied from interface: PropertyGraph.Vertex

Ensures this vertex connects to the vertex with an 'id' property equal to the target parameter. The edge or vertex is created if needed. This vertex is returned.

If a vertex is created its 'id' property will be set to the target parameter. If an edge is created the source property is set to the 'id' of this vertex and the target property is set to the 'id' of the target vertex.

If this graph is undirected and contains an edge connecting this vertex with target the edge will not be created. Undirected graphs ignore source/target order in edges.

target - vertex id

Returns:

this vertex

connectsFrom

public PropertyGraph.Vertex<ID> connectsFrom(ID source)

Description copied from interface: PropertyGraph.Vertex

Ensures this vertex connects to the vertex with an id property equal to the source parameter. The edge or vertex is created if needed. This vertex is returned.

If a vertex is created its id property will be set to the source parameter. If an edge is created the target property is set to the id of the source vertex and the target property is set to the id of this vertex.

If this graph is undirected and contains an edge connecting this vertex with source the edge will not be created. Undirected graphs ignore source/target order in edges.
