How to use the rdf-ext.createTriple function in rdf-ext

this.graph.add(rdf.createTriple(this.iri, predicate, value))
        } else {
          this.graph.add(rdf.createTriple(this.iri, predicate, value._core.iri))

          // don't cache array values, because we cache the complete array
          if (!options.array) {
            this.objects[predicate] = value
          }
        }
      } else if (typeof value === 'boolean') {
        this.graph.add(rdf.createTriple(
          this.iri,
          predicate,
