Detailed Description

Implementation of the AbstractCombigridStorage using TreeStorage<TreeStorage<float_t>>.

Constructor & Destructor Documentation

◆ CombigridTreeStorage() [1/2]

sgpp::combigrid::CombigridTreeStorage::CombigridTreeStorage	(	std::vector< std::shared_ptr< AbstractPointHierarchy >> const &	p_pointHierarchies,
		MultiFunction	p_func
	)

Parameters

p_pointHierarchies	Point hierarchies generating the points at which the function should be evaluated.
p_func	Function generating the values that are stored in the storage.

◆ CombigridTreeStorage() [2/2]

sgpp::combigrid::CombigridTreeStorage::CombigridTreeStorage	(	std::vector< std::shared_ptr< AbstractPointHierarchy >> const &	p_pointHierarchies,
		bool	exploitNesting = `true`,
		MultiFunction	p_func = `MultiFunction(constantFunction<base::DataVector const &, double>())`
	)

Parameters

p_pointHierarchies	Point hierarchies generating the points at which the function should be evaluated.
exploitNesting	If this is set to true, identical grid points on different levels can have different values. This is e.g. relevant for PDE solving.
p_func	Function generating the values that are stored in the storage.

◆ deserialize()

void sgpp::combigrid::CombigridTreeStorage::deserialize ( std::string const & str )

Re-loads storage values from a string that has been generated by serialize().

◆ getGuidedIterator()

std::shared_ptr< AbstractMultiStorageIterator< double > > sgpp::combigrid::CombigridTreeStorage::getGuidedIterator	(	MultiIndex const &	level,
		MultiIndexIterator &	iterator,
		std::vector< bool >	orderingConfiguration
	)

virtual

Parameters

level	Level to traverse
iterator	Iterator that defines which values should be iterated over
orderingConfiguration	Defines for each dimension whether the grid points in that dimension should be traversed in sorted order.

Returns: Returns an iterator that iterates along the multi-indices for a given level. These multi-indices are given by the parameter iterator. When moveToNext() is called on the returned iterator, it also calls moveToNext() on the underlying MultiIndexIterator. If the values are not already stored, they are created during iteration.

Implements sgpp::combigrid::AbstractCombigridStorage.
