Xpetra: missing access routine getData for Xpetra::Vector

Created by: mayrmt

@trilinos/xpetra @lucbv

Expectations

It might be desired to have a specialized access routine getData() for the Xpetra::Vector that does not call the base class routine in Xpetra::MultiVector.

Current Behavior

To access the data in a Xpetra::Vector, one has to call the base class routine with argument getData(0) to access the data of the very first column in the multivector, although it is clear that the Xpetra::Vector only has one column.

Motivation and Context

This would emphasize the fact that the Xpetra::Vector just has one column and make it more convenient to access its data.

Definition of Done

  • add getData() and getDataNonConst() to Xpetra::Vector class
  • add documentation
  • add test

Possible Solution

The Xpetra::Vector::getData() could just call Xpetra::MultiVector::getData(0).

Additional Information

Please let me know if this idea is total nonsense or if there are reasons to not do that.
