class LinearAlgebraObject

Parent class(es)

• Variable

This is a common base class for all DOLFIN linear algebra objects. In particular, it provides casting mechanisms between different types.

const T& down_cast() const

Cast object to its derived class, if possible (const version). An error is thrown if the cast is unsuccessful.

T& down_cast()

Cast object to its derived class, if possible (non-const version). An error is thrown if the cast is unsuccessful.

static std::shared_ptr<X> down_cast(std::shared_ptr<Y> A)

Cast shared pointer object to its derived class, if possible. Caller must check for success (returns null if cast fails).

const LinearAlgebraObject* instance() const

Return concrete instance / unwrap (const version)

LinearAlgebraObject* instance()

Return concrete instance / unwrap (non-const version)

std::shared_ptr<const LinearAlgebraObject> shared_instance() const

Return concrete shared ptr instance / unwrap (const version)

std::shared_ptr<LinearAlgebraObject> shared_instance()

Return concrete shared ptr instance / unwrap (non-const version)

Y& as_type(X& x)

Cast object to its derived class, if possible (non-const version). An error is thrown if the cast is unsuccessful.

std::shared_ptr<Y> as_type(std::shared_ptr<X> x)

Cast shared pointer object to its derived class, if possible. Caller must check for success (returns null if cast fails).

bool has_type(const X& x)

Check whether the object matches a specific type
