Detailed Description

Class that holds a generic rectangular tiling.

Constructor & Destructor Documentation

fastjet::RectangularGrid::RectangularGrid ( double  rapmax_in, double  cell_size  )

inline

ctor with simple initialisation

Parameters

rapmax	the maximal absolute rapidity extent of the grid
cell_size	the grid spacing (equivalently, cell size)

Definition at line 93 of file RectangularGrid.hh.

fastjet::RectangularGrid::RectangularGrid ( double  rapmin_in, double  rapmax_in, double  drap_in, double  dphi_in, Selector  tile_selector = Selector()  )

inline

ctor with more control over initialisation

Parameters

rapmin	the minimum rapidity extent of the grid
rapmax	the maximum rapidity extent of the grid
drap	the grid spacing in rapidity
dphi	the grid spacing in azimuth
tile_selector	optional (geometric) selector to specify which tiles are good; a tile is good if a massless 4-vector at the center of the tile passes the selection

Definition at line 108 of file RectangularGrid.hh.

Member Function Documentation

virtual int fastjet::RectangularGrid::n_tiles ( ) const

inlinevirtual

returns the total number of tiles in the tiling; valid tile indices run from 0 ...

n_tiles()-1;

Implements fastjet::TilingBase.

Definition at line 120 of file RectangularGrid.hh.

virtual int fastjet::RectangularGrid::n_good_tiles ( ) const

inlinevirtual

returns the number of tiles that are "good"; i.e.

there is scope for having tiles that, for whatever reason, should be ignored; there are situations in which having "non-good" tiles may be the simplest mechanism to obtain a tiling with holes in it

Reimplemented from fastjet::TilingBase.
