Detailed Description

template<class Scalar>
class Thyra::SpmdMultiVectorBase< Scalar >

Base interface class for SPMD multi-vectors.

By inheriting from this base class, multi-vector implementations allow their multi-vector objects to be seamlessly combined with other SPMD multi-vector objects (of different concrete types) in applyOp() and apply(). A big part of this protocol is that every multi-vector object can expose an SpmdVectorSpaceBase object through the function spmdSpace().
