## Member Function Documentation

void voro::container_periodic::clear | ( |  | ) |

Clears a container of particles.

Definition at line 448 of file container_prd.cc.

void voro::container_periodic::compute_all_cells | ( |  | ) |

Computes all of the Voronoi cells in the container, but does nothing with the output. It is useful for measuring the pure computation time of the Voronoi algorithm, without any additional calculations such as volume evaluation or cell output.

Definition at line 499 of file container_prd.cc.

template<class v_cell , class c_loop >

bool voro::container_periodic::compute_cell | ( | v_cell & | c,
|  | c_loop & | vl
| ) |  |
| inline

Computes the Voronoi cell for a particle currently being referenced by a loop class.

Parameters

  [out] | c | a Voronoi cell class in which to store the computed cell.
  [in] | vl | the loop class to use.

Returns
  True if the cell was computed. If the cell cannot be computed because it was removed entirely for some reason, then the routine returns false.

Definition at line 388 of file container_prd.hh.

template<class v_cell >

bool voro::container_periodic::compute_cell | ( | v_cell & | c,
|  | int | ijk,

  [in] | ijk | the block that the particle is within.
  [in] | q | the index of the particle within the block.

Returns
  True if the cell was computed. If the cell cannot be computed because it was removed entirely for some reason, then the routine returns false.

Definition at line 400 of file container_prd.hh.

template<class v_cell >

bool voro::container_periodic::compute_ghost_cell | ( | v_cell & | c,

Parameters

  [out] | c | a Voronoi cell class in which to store the computed cell.
