Detailed Description

template<class Scalar>
class Thyra::VectorSpaceDefaultBase< Scalar >

Node VectorSpaceBase subclass that provides default implementations for many functions using a default multi-vectors implementation.

Notes to Subclass Developers

Because of the default multi-vector implementation used in this node subclasses, a concrete subclass is only required to override four functions: dim(), isCompatible(), createMember() and smallVecSpcFcty(). Note that implementing the createMember() method also entails defining a concrete VectorBase subclass and defining smallVecSpcFcty() entails defining a concrete VectorSpaceFactoryBase subclass.

If a subclass can support specialized multi-vectors, then the createMembers() function should be overridden as well. Note that implementing createMembers() also entails defining a concrete MultiVectorBase subclass.

template<class Scalar >
Teuchos::RCP< MultiVectorBase< Scalar > > Thyra::VectorSpaceDefaultBase< Scalar >::createMembers ( int  numMembers) const
protectedvirtual

The default implementation returns dynamic_cast< DefaultColumnwiseMultiVector<Scalar> >(return.get())!=NULL.

Implements Thyra::VectorSpaceBase< Scalar >.

Reimplemented in Thyra::DefaultClusteredSpmdProductVectorSpace< Scalar >, Thyra::DefaultSpmdVectorSpace< Scalar >, and Thyra::TpetraVectorSpace< Scalar, LocalOrdinal, GlobalOrdinal, Node >.

template<class Scalar >
Teuchos::RCP< VectorBase< Scalar > > Thyra::VectorSpaceDefaultBase< Scalar >::createMemberView ( const RTOpPack::SubVectorView< Scalar > &  raw_v) const
protectedvirtual

The default implementation of this function simply calls this->createMember() to create a vector then uses the explicit element access functions to set the elements and then only when the vector is destroyed is the data copied out of the vector and back into the elements pointed to by raw_v.values().

Implements Thyra::VectorSpaceBase< Scalar >.

template<class Scalar >
Teuchos::RCP< const VectorBase< Scalar > > Thyra::VectorSpaceDefaultBase< Scalar >::createMemberView ( const RTOpPack::ConstSubVectorView< Scalar > &  raw_v) const
protectedvirtual

The default implementation of this function simply calls this->createMember() to create a vector then uses the explicit element access functions to set the elements from raw_v.values().

Implements Thyra::VectorSpaceBase< Scalar >.

Reimplemented in Thyra::DefaultSpmdVectorSpace< Scalar >.

template<class Scalar >
Teuchos::RCP< MultiVectorBase< Scalar > > Thyra::VectorSpaceDefaultBase< Scalar >::createMembersView ( const RTOpPack::SubMultiVectorView< Scalar > &  raw_mv) const
protectedvirtual

The default implementation of this function simply calls this->createMembers(raw_mv.numSubCols()) to create a multi-vector then uses the explicit element access functions to set the elements and then only when the multi-vector is destroyed is the data copied out of the multi-vector and back into the elements pointed to by raw_mv.values().
