Definition at line 46 of file Thyra_VectorSpaceDecl.hpp.

Member Function Documentation

template<class Scalar>
Vector< Scalar > Thyra::VectorSpace< Scalar >::createMember (   )  const [inline]
 

Create a new element of this vector space.

Definition at line 59 of file Thyra_VectorSpaceImpl.hpp.

template<class Scalar>
RefCountPtr< MultiVectorBase< Scalar > > Thyra::VectorSpace< Scalar >::createMembers (  int  n  )  const [inline]
 

Create a multivector in this vector space.

Note: There is not yet a handle class for multi-vectors yet and therefore this function returns Teuchos::RefCountPtr object to the created raw MultiVectorBase object. In the future, this will be replaced to return a true Thyra::MultiVector handle object onces this class is created.

Definition at line 66 of file Thyra_VectorSpaceImpl.hpp.

template<class Scalar>
int Thyra::VectorSpace< Scalar >::dim (   )  const [inline]
 

Return the dimension of the space.

Definition at line 65 of file Thyra_VectorSpaceDecl.hpp.

template<class Scalar>
bool Thyra::VectorSpace< Scalar >::isCompatible (  const VectorSpace< Scalar > &  vecSpc  )  const [inline]
 

Check compatibility with another space.

Implementation note: we don't know if the argument vec space is a handle to another vector space or the contents of a handle, and we want the operation to work the same in either case. We can make this work as follows: have the argument check compatibility with the contents of this handle. If the argument is a handle, the process will be repeated, interchanging places again so that both handles are dereferenced. If the argument is not a handle, then it ends up comparing to the concrete contents of this handle, giving the same results.
