◆ IntegrationPointWriter() [1/2]

template<typename LocalAssemblerInterface , typename... Args>

MeshLib::IntegrationPointWriter::IntegrationPointWriter	(	std::string const &	name,
		int const	n_components,
		int const	integration_order,
		std::vector< std::unique_ptr< LocalAssemblerInterface > > const &	local_assemblers,
		std::vector< double >(LocalAssemblerInterface::*	getIpData )(Args...) const,
		Args &&...	args )

inline

Constructor taking a member function of the LocalAssemblerInterface as a callback.

The callback getIpData must return a std::vector<double>.

◆ IntegrationPointWriter() [2/2]

template<typename LocalAssemblerInterface , typename Accessor >

MeshLib::IntegrationPointWriter::IntegrationPointWriter	(	std::string const &	name,
		int const	n_components,
		int const	integration_order,
		std::vector< std::unique_ptr< LocalAssemblerInterface > > const &	local_assemblers,
		Accessor	accessor )

inline

Constructor taking an accessor function as a callback.

The accessor function must take a const reference to a LocalAssemblerInterface object as its only argument. The callback accessor must return a std::vector<double>.
