abstract class AbstractRDFGraph[T, G <: AbstractRDFGraph[T, G]] extends AnyRef

A data structure that comprises a collection of triples. Note, due to the implementation of the Spark datastructures, this doesn't necessarily mean to be free of duplicates which is why a distinct operation is provided.
