Member Function Documentation

computePoints()

std::vector< double > & sgpp::combigrid::NonNestedPointHierarchy::computePoints ( size_t  level )

virtual

References getNumPoints(), level, pointDistribution, pointOrdering, and points.

Referenced by getPoint(), getPoints(), and getSortedPermutationIterator().

getNumPoints()

size_t sgpp::combigrid::NonNestedPointHierarchy::getNumPoints ( size_t  level )

virtual

Returns

Returns the number of points in the given level.

Implements sgpp::combigrid::AbstractPointHierarchy.

References level, numPointsPerLevel, and pointOrdering.

Referenced by computePoints(), and getSortedPermutationIterator().

getPoint()

double sgpp::combigrid::NonNestedPointHierarchy::getPoint ( size_t  level, size_t  index  )

virtual

Returns

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

Implements sgpp::combigrid::AbstractPointHierarchy.

References computePoints().

getPoints()

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

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.

Implements sgpp::combigrid::AbstractPointHierarchy.

References computePoints(), getSortedPermutationIterator(), python.statsfileInfo::i, and points.

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

getSortedPermutationIterator()

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

virtual

Returns

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

Implements sgpp::combigrid::AbstractPointHierarchy.

References computePoints(), getNumPoints(), level, permutationIterators, pointOrdering, and points.

Referenced by getPoints().

isNested()

bool sgpp::combigrid::NonNestedPointHierarchy::isNested ( )

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.

Implements sgpp::combigrid::AbstractPointHierarchy.
