## Detailed Description

When particles are added to a container class, they are sorted into an internal computational grid of blocks. The particle_order class provides a mechanism for remembering which block particles were sorted into. The import and put routines in the container class have variants that also take a particle_order class. Each time they are called, they will store the block that the particle was sorted into, plus the position of the particle within the block. The particle_order class can used by the c_loop_order class to specifically loop over the particles that have their information stored within it.

## Constructor & Destructor Documentation

voro::particle_order::particle_order | ( | int | init_size = `init_ordering_size` | ) |
| inline

The particle_order constructor allocates memory to store the ordering information.

Parameters

  [in] | init_size | the initial amount of memory to allocate.

Definition at line 51 of file c_loops.hh.

voro::particle_order::~particle_order | ( |  | ) |
| inline

The particle_order destructor frees the dynamically allocated memory used to store the ordering information.

Definition at line 55 of file c_loops.hh.

## Member Function Documentation

void voro::particle_order::add | ( | int | ijk,
|  | int | q
| ) |  |
| inline

Adds a record to the order, corresponding to the memory address of where a particle was placed into the container.

Parameters

  [in] | ijk | the block into which the particle was placed.
  [in] | q | the position within the block where the particle was placed.
