Detailed Description

template<class Scalar>
class Thyra::VectorDefaultBase< Scalar >

Convenient node subclass for concrete VectorBase subclasses that relies on a default MultiVectorBase implementation.

This node subclass provides as many default implementations as possible for virtual functions based on the default multi-vector implementation DefaultColumnwiseMultiVector.

Notes for subclass developers

In order to create a concrete subclass of this interface, only two operations must be overridden: space() and applyOp(). Overriding the space() operation requires defining a concrete VectorSpaceBase class (which has only three pure virtual operations if using VectorSpaceDefaultBase).

Note that all of the inherited LinearOpBase and MultiVectorBase functions are overridden in this subclass and are given perfectly good implementations. Therefore, a concrete subclass of VectorDefaultBase should not have to re-override any of these functions.

template<class Scalar>
std::string Thyra::VectorDefaultBase< Scalar >::description (  )  const [virtual]

Default description that gives the label, type, and dimenstion .

Reimplemented from Thyra::LinearOpDefaultBase< Scalar >.

Reimplemented in Thyra::DefaultMultiVectorProductVector< Scalar >, Thyra::DefaultProductVector< Scalar >, and Thyra::SpmdVectorBase< Scalar >.

template<class Scalar>
void Thyra::VectorDefaultBase< Scalar >::describe ( Teuchos::FancyOStream out,
const Teuchos::EVerbosityLevel  verbLevel 
) const [virtual]

Generates a default outputting for all vectors.

Calls on the this->describe(void) function for the name of the class (and possibly its instance name) and then if verbLevel>=VERB_HIGH, then the vector elements themselves are printed as well. The format of the output is is shown below:

   type = 'this->description()', size = n
     0:x1
     1:x2
     .
     .
     .
     n-1:xn
   

The index:value lines are offset an additional Teuchos::OSTab amount. A newline is printed after the last n-1:xn entry.

template<class Scalar>
void Thyra::VectorDefaultBase< Scalar >::acquireDetachedVectorViewImpl ( const Range1D rng,
RTOpPack::ConstSubVectorView< Scalar > *  sub_vec 
) const [virtual]

This implementation is based on a vector reduction operator class (see RTOpPack::ROpGetSubVector) and calls applyOp(). Note that the footprint of the reduction object (both internal and external state) will be O(rng.size()). For serial applications this is fairly reasonable and will not be a major performance penalty. For parallel applications, however, this is a terrible implementation and must be overridden if rng.size() is large at all. Although, this function should not even be used in case where the vector is very large. If a subclass does override this function, it must also override releaseDetachedView() which has a implementation which is a companion to this function's implementation.

template<class Scalar>
void Thyra::VectorDefaultBase< Scalar >::releaseDetachedVectorViewImpl ( RTOpPack::ConstSubVectorView< Scalar > *  sub_vec  )  const [virtual]

This implementation is a companion to the implementation for the non-const version of acquireDetachedView(). If acquireDetachedView() is overridden by a subclass then this function must be overridden also!

Implements Thyra::VectorBase< Scalar >.

For serial applications this is fairly reasonable and will not be a major performance penalty.

This function has an implementation which is a companion to the implementation for acquireDetachedView(). If acquireDetachedView() is overridden by a subclass then this function must be overridden also!

template<class Scalar>
void Thyra::VectorDefaultBase< Scalar >::setSubVector ( const RTOpPack::SparseSubVectorT< Scalar > &  sub_vec  )  [virtual]

This implementation uses a transformation operator class (see RTOpPack::TOpSetSubVector) and calls applyOp(). Be forewarned however, that the operator objects state data (both internal and external) will be order O(sub_vec.subNz()). For serial applications, this is entirely adequate. For parallel applications this may be bad!
