Detailed Description

template<class Scalar>
class Thyra::MPIVectorStd< Scalar >

Efficient concrete implementation subclass for SPMD-MPI-based vectors.

This subclass provides a very efficient and very general concrete implementation of a Thyra::VectorBase object.

Objects of this type generally should not be constructed directly by a client but instead by using the concrete vector space subclass Thyra::MPIVectorSpaceStd and using the function Thyra::MPIVectorSpaceStd::createMember().

The storage type can be anything since a Teuchos::RefCountPtr is used to pass in the local values pointer into the constructor and initialize().

template<class Scalar> void Thyra::MPIVectorStd< Scalar >::initialize (  const Teuchos::RefCountPtr< const MPIVectorSpaceBase< Scalar > > &  mpiSpace, const Teuchos::RefCountPtr< Scalar > &  localValues, const Index  stride )

Initialize. Parameters: mpiSpace  [in] Smart pointer to MPIVectorSpaceBase object that defines the data distribution for mpiSpace() and space(). localValues  [in] Smart pointer to beginning of local strided vector data. This array must be at least of dimension mpiRangeSpace->localDim()*stride and (&*localValues)[ (i-1)*stride ] gives the local value of the one-based entry (i) where i=1...mpiSpace()->localSubDim(). stride  [in] Stride between local vector elements. Preconditions: mpiSpace.get()!=NULL localValues.get()!=NULL stride != 0 Postconditions: this->getRCptr().get() == localValues.get() this->getPtr() == &*localValues this->getStride() == stride Definition at line 56 of file Thyra_MPIVectorStd.hpp.

Set to an uninitialized state. Postconditions: this->mpiSpace().get() == NULL. Definition at line 74 of file Thyra_MPIVectorStd.hpp.
