TripleGraph

scalation.database.triplegraph.TripleGraph
case class TripleGraph(label: Array[ValueType], triples: ArrayBuffer[Triple], name: String, schema: Array[String]) extends Cloneable

The TripleGraph class stores vertex/edge-labeled triple graphs by maintaining bags of vertices and triples.

Value parameters

label

the array of vertex labels

name

the name of the triple-graph

schema

optional schema: map from label to label type

triples

the bag of triples in the triple-graph
