[Trilinos-Users] Tpetra::Vector: elementwise operations

thinking about Tpetra vectors, I was asking myself if there's any better
way to do elementwise operations (e.g., sqrt(), conj(),...) than what I do
at the moment:

===================== *snip* =====================
Teuchos::ArrayRCP<const double> inVectorView = inVector.get1dView();
for (int k=0; k<NumLocalElements; k++ ) {
   int globalIndex = Map->getGlobalElement(k);
   outVector->replaceLocalValue( k, 0, inVectorView[globalIndex] );
===================== *snap* =====================

As far as I can see, there's no such method as getLocalValue{s}(). Am I
