Detailed Description

This class can loop over a subset of particles in a certain geometrical region within the container. The class can be set up to loop over a rectangular box or sphere. It can also rectangular group of internal computational blocks.

Constructor & Destructor Documentation

template<class c_class >

voro::c_loop_subset::c_loop_subset ( c_class & con )

inline

The constructor copies several necessary constants from the base container class.

Parameters

[in] con the container class to use.

Definition at line 228 of file c_loops.hh.

Member Function Documentation

bool voro::c_loop_subset::inc ( )

inline

Finds the next particle to test.

Returns: True if there is another particle, false if no more particles are available.

Definition at line 238 of file c_loops.hh.

void voro::c_loop_subset::setup_box	(	double	xmin,
		double	xmax,
		double	ymin,
		double	ymax,
		double	zmin,
		double	zmax,
		bool	bounds_test = `true`
	)

Initializes the class to loop over all particles in a rectangular box.

Parameters

[in]	(xmin,xmax)	the minimum and maximum x coordinates of the box.
[in]	(ymin,ymax)	the minimum and maximum y coordinates of the box.
[in]	(zmin,zmax)	the minimum and maximum z coordinates of the box.
[in]	bounds_test	whether to do detailed bounds checking. If this is false then the class will loop over all particles in blocks that overlap the given box. If it is true, the particle will only loop over the particles which actually lie within the box.

Returns: True if there is any valid point to loop over, false otherwise.

Definition at line 98 of file c_loops.cc.

void voro::c_loop_subset::setup_intbox	(	int	ai_,
		int	bi_,
		int	aj_,
		int	bj_,
		int	ak_,
		int	bk_
	)

Initializes the class to loop over all particles in a rectangular subgrid of blocks.

Parameters

[in]	(ai_,bi_)	the subgrid range in the x-direction, inclusive of both ends.
[in]	(aj_,bj_)	the subgrid range in the y-direction, inclusive of both ends.
[in]	(ak_,bk_)	the subgrid range in the z-direction, inclusive of both ends.

Returns: True if there is any valid point to loop over, false otherwise.

Definition at line 44 of file c_loops.cc.

void voro::c_loop_subset::setup_sphere	(	double	vx,
		double	vy,
		double	vz,
		double	r,
		bool	bounds_test = `true`
	)

Initializes a c_loop_subset object to scan over all particles within a given sphere.

Parameters

[in]	(vx,vy,vz)	the position vector of the center of the sphere.
[in]	r	the radius of the sphere.
[in]	bounds_test	whether to do detailed bounds checking. If this is false then the class will loop over all particles in blocks that overlap the given sphere. If it is true, the particle will only loop over the particles which actually lie within the sphere.

Returns: True if there is any valid point to loop over, false otherwise.

Definition at line 24 of file c_loops.cc.

bool voro::c_loop_subset::start ( )

Starts the loop by finding the first particle within the container to consider.

Returns: True if there is any particle to consider, false otherwise.

Definition at line 79 of file c_loops.cc.

Field Documentation

c_loop_subset_mode voro::c_loop_subset::mode

The current mode of operation, determining whether tests should be applied to particles to ensure they are within a certain geometrical object.
