Confused by code

[kwalcock]

@enoriega,

Can you explain the code at

processors/library/src/main/scala/org/clulab/serialization/DocumentSerializer.scala

Lines 110 to 118 in a589771

	// TODO: Hack by Enrique to resolve the document object for the relations
	for(sen <- doc.sentences){
	sen.relations match {
	case Some(relations) =>
	val newRelations = relations.map(r => RelationTriple(r.confidence, r.subjectInterval, r.relationInterval, r.objectInterval))
	sen.relations = Some(newRelations)
	case None => ()
	}
	}

?

It seems like it is just making a copy of all the relations in a sentence and writing them back to the sentence. Is there some side effect that I am missing? Thanks.
