Detailed Description

Point Search Utility functions for finding points in a grid based on provided coordinate information.

Constructor & Destructor Documentation

PointSearch()

Fiber::PointSearch::PointSearch	(	Slice &	slice,
		Grid &	TheGrid,
		const string &	Gridname
	)

1. Create a helper Grid object
2. Modifies the Grid object and creates a relative representation in the cells of the helper Grid.

References CellID(), FragmentBoxes, and HelperGridname().

Member Function Documentation

CellID()

static SkeletonID Fiber::PointSearch::CellID ( const Grid &  G )

inlinestatic

Return the skeleton ID which is used to cell information.

A cell is an atomic set of vertices (therefore index depth 1) and of the same dimensionality of the vertices.

getHelperField()

RefPtr< Field > Fiber::PointSearch::getHelperField ( const RefPtr< Slice > &  slice, const RefPtr< Grid > &  TheGrid, const string &  Gridname  )

static

Global high-level functions to inspect whether a certain Grid has a point search helper field.

Use in combination with hasLookupFragment() to check if there is information about a certain fragment.

References CellID(), std::cout, std::endl(), and HelperGridname().

HelperGridname()

static string Fiber::PointSearch::HelperGridname ( const string &  Gridname )

inlinestatic

The point search stores lookup information in another Grid object on the same slice.

It will be stored under the name as provided by this function.
