Public Member Functions

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

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

  
  

Static Public Member Functions

• static string HelperGridname (const string &Gridname)

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

• static SkeletonID CellID (const Grid &G)

  Return the skeleton ID which is used to cell information.
  

• static RefPtr< Field > getHelperField (const RefPtr< Slice > &slice, const RefPtr< Grid > &TheGrid, const string &Gridname)

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

• static bool hasLookupFragment (const RefPtr< Field > &HelperFeld, const RefPtr< FragmentID > &f)

  Global function to check if the given HelperField has information stored about the specific fragment ID.
  

Public Attributes

• RefPtr< Field > UniMapperField
• RefPtr< Field > FragmentBoxes

  The cartesian positions of the helper grid, containing the bounding boxes of each fragment in the original grid.

static SkeletonID Fiber::PointSearch::CellID

(

const Grid &

G

)

[inline, static]

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.

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.

static string Fiber::PointSearch::HelperGridname

(

const string &

Gridname

)

[inline, static]

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.
