Detailed Description

template<typename T = int, int MAXDIM = 10>
struct npl::Counter< T, MAXDIM >

Very basic counter that iterates over an ND region.

Example usage:

size_t ret = 0; size_t width = 5; Counter c; c.ndim = ndim; for(size_t ii=0; ii<ndim; ii++) c.sz[ii] = width;

do { double weight = 1; for(int dd = 0; dd < ndim; dd++) weight *= c.pos[dd]; } while(c.advance());

Template Parameters

T	Type of size/position
MAXDIM	Maximum supported dimension, static array will be this size

Constructor & Destructor Documentation

template<typename T = int, int MAXDIM = 10>

npl::Counter< T, MAXDIM >::Counter ( size_t  dim )

inline

Default constructor. Just sizes pos to 0. dim is the number of dimensions to use/iterate over.

Parameters

dim

Definition at line 544 of file basic_functions.h.

template<typename T = int, int MAXDIM = 10>

npl::Counter< T, MAXDIM >::Counter ( size_t  dim, const T *  stop  )

inline

Initialize counter with the specified dimension and stop point.

Parameters

dim	Number of dimensions
stop

Member Function Documentation

template<typename T = int, int MAXDIM = 10>

bool npl::Counter< T, MAXDIM >::advance ( bool  rorder = false )

inline

Advance through ND-counter. 0,0,0 to 0,0,1 and so on. If roder is true then this will start at 0,0,0 and then go to 1,0,0 then 2,0,0, etc.

Parameters

rorder

Whether to reverse the order and do low dimension fastest

Returns
