Edge

scalation.database.graph.Edge
See theEdge companion object
class Edge(_name: String, val from: Vertex, val prop: Property, val to: Vertex, val shift: Int) extends Identifiable, Spatial, Serializable

The Edge class maintains the edge's connections between vertices as well as its own properites. An edge is roughly analogous to implicit relationship manifest via foreign key-primary key pairs. The parameters may be thought of like a triple, e.g., (h, r, t) or (s, p, o).

Value parameters

_name

the name of this edge ('name' from Identifiable), edge label

from

this edge's source/from vertex

prop

maps edge's property names into property values

shift

number of units to shift to accomodate a bundle of egdes in a composite edge

to

this edge's target/to vertex
