template<class Derived>
Rodin::Variational::FunctionBase class

Base class for function objects which can be evaluated over a mesh.

Base class for functions defined on a mesh.

Instances of FunctionBase will always have the getValue() method defined, which enables the evaluation of any function on some mesh element.

Public functions

auto getTraceDomain() const -> const TraceDomain& constexpr
Gets the set of attributes which will be interpreted as the domains to "trace".
auto getValue(const Geometry::Point& p) const -> auto constexpr
Evaluates the function on a Point belonging to the mesh.
auto operator()(const Geometry::Point& p) const -> auto constexpr
Evaluates the function on a Point belonging to the mesh.
auto traceOf(Geometry::Attribute attr) -> Derived& constexpr
Sets an attribute which will be interpreted as the domain to trace.
auto copy() const -> FunctionBase* override noexcept
Copies the object and returns a non-owning pointer to the copied object.

Function documentation

template<class Derived>
const TraceDomain& Rodin::Variational::FunctionBase<Derived>::getTraceDomain() const constexpr

Gets the set of attributes which will be interpreted as the domains to "trace".

The domains to trace are interpreted as the domains where there shall be a continuous extension from values to the interior boundaries. If the trace domain is empty, then this has the semantic value that it has not been specified yet.

template<class Derived>
auto Rodin::Variational::FunctionBase<Derived>::getValue(const Geometry::Point& p) const constexpr

Evaluates the function on a Point belonging to the mesh.

template<class Derived>
auto Rodin::Variational::FunctionBase<Derived>::operator()(const Geometry::Point& p) const constexpr

Evaluates the function on a Point belonging to the mesh.

This calls the function get getValue(const Geometry::Point&).

template<class Derived>
Derived& Rodin::Variational::FunctionBase<Derived>::traceOf(Geometry::Attribute attr) constexpr

Sets an attribute which will be interpreted as the domain to trace.

Returns Reference to self (for method chaining)

Convenience function to call traceOf(FlatSet<int>) with only one attribute.

template<class Derived>
FunctionBase* Rodin::Variational::FunctionBase<Derived>::copy() const override noexcept

Copies the object and returns a non-owning pointer to the copied object.

Returns Non-owning pointer to the copied object.
