Detailed Description

template<typename V>
class sgpp::combigrid::FullGridCallbackEvaluator< V >

Implementation of the AbstractFullGridLinearEvaluator class using a callback function that takes a single point and returns a function value at that point.

Constructor & Destructor Documentation

FullGridCallbackEvaluator()

template<typename V >

sgpp::combigrid::FullGridCallbackEvaluator< V >::FullGridCallbackEvaluator ( std::shared_ptr< AbstractCombigridStorage >  storage, std::vector< std::shared_ptr< AbstractLinearEvaluator< V >>>  evaluatorPrototypes, std::vector< std::shared_ptr< AbstractPointHierarchy >>  pointHierarchies, FullGridSummationStrategyType  summationStrategyType = FullGridSummationStrategyType::LINEAR  )

inline

Constructor.

Parameters

storage	Storage that stores and provides the function values for each grid point.
evaluatorPrototypes	prototype objects for the evaluators that are cloned to get an evaluator for each dimension and each level.
pointHierarchies	PointHierarchy objects for each dimension providing the points for each level and information about their ordering.
summationStrategyType	strategy to gather the results of the univariate evaluators on each anisotropic full grid

Member Function Documentation

eval()

template<typename V >

V sgpp::combigrid::FullGridCallbackEvaluator< V >::eval ( MultiIndex const &  level )

inlineoverridevirtual

Evaluates the function given through the storage for a certain level-multi-index (see class description).

Implements sgpp::combigrid::AbstractFullGridEvaluator< V >.

getLevelTasks()

template<typename V >

std::vector<ThreadPool::Task> sgpp::combigrid::FullGridCallbackEvaluator< V >::getLevelTasks ( MultiIndex const &  level, ThreadPool::Task  callback  )

inlinevirtual

Returns

a vector of tasks which can be precomputed in parallel to make the (serialized) execution of eval() faster

Parameters

level	the level which one wants to compute
callback	This callback is called (with already locked mutex) from inside one of the returned tasks when all tasks for the given level are completed and the level can be added.

Implements sgpp::combigrid::AbstractFullGridEvaluator< V >.
