Detailed Description

Contains all the necessary information about a family of one-dimensional grids:

• Point distribution
• Level-numPoints-mapping
• Point sorting
• Hierarchy information

Derived classes of AbstractPointHierarchy also save the grid points, avoiding expensive re-computation.

Member Function Documentation

getNumPoints()

virtual size_t sgpp::combigrid::AbstractPointHierarchy::getNumPoints ( size_t  level )

pure virtual

Returns

Returns the number of points in the given level.

Implemented in sgpp::combigrid::NestedPointHierarchy, and sgpp::combigrid::NonNestedPointHierarchy.

getPoint()

virtual double sgpp::combigrid::AbstractPointHierarchy::getPoint ( size_t  level, size_t  index  )

pure virtual

Returns

Returns the grid point for the given level and index. (0 <= index < getNumPoints(level))

Implemented in sgpp::combigrid::NestedPointHierarchy, and sgpp::combigrid::NonNestedPointHierarchy.

getPoints()

virtual std::vector<double> sgpp::combigrid::AbstractPointHierarchy::getPoints ( size_t  level, bool  sorted  )

pure virtual

Returns

Returns a vector with all points for the given level. If sorted == true, then the points returned are sorted. Depending on the configured PointOrdering, this might be slower than not sorting the points.

Implemented in sgpp::combigrid::NestedPointHierarchy, and sgpp::combigrid::NonNestedPointHierarchy.

Referenced by python.data.DataContainer.DataContainer::combine(), python.data.DataContainer.DataContainer::getDataSubsetByIndexList(), python.data.DataContainer.DataContainer::getPointsValues(), and python.data.DataContainer.DataContainer::toString().

getSortedPermutationIterator()

virtual std::shared_ptr<AbstractPermutationIterator> sgpp::combigrid::AbstractPointHierarchy::getSortedPermutationIterator ( size_t  level )

pure virtual

Returns

Returns a permutation iterator which can be used to traverse the points in their sorted (ascending) order.

Implemented in sgpp::combigrid::NestedPointHierarchy, and sgpp::combigrid::NonNestedPointHierarchy.

isNested()

virtual bool sgpp::combigrid::AbstractPointHierarchy::isNested ( )

pure virtual

Returns

Returns true if the points of a level are always a subset of the points at the next level. This should also mean that the points that are common to two levels share the same indices.

Implemented in sgpp::combigrid::NestedPointHierarchy, and sgpp::combigrid::NonNestedPointHierarchy.
