Detailed Description

template<typename T>
class PeriodicLookup< T >

O(1) look-up table for finding periodic image within symmThreshold Needs a companion function vector3<> getCoord(T) that returns the lattice coordinates corresponding to type T

Constructor & Destructor Documentation

PeriodicLookup()

template<typename T >

PeriodicLookup< T >::PeriodicLookup ( const std::vector< T > &  points, matrix3<>  metric, size_t  nPointsTarget = 0  )

inline

Initialize given an array of points and a metric corresponding to the lattice coordinates (optionally override the number of points, if the points array is to be dynamically grown)

Member Function Documentation

addPoint()

template<typename T >

void PeriodicLookup< T >::addPoint ( size_t  iPoint, const T &  point  )

inline

Call every time a point is added to the end of the points vector externally. Note that points may only be added to the end of the vector (otherwise some of the existing indices are invalidated!)

find()

template<typename T >

template<typename Tag = double, typename TagEquality = std::equal_to<Tag>>

size_t PeriodicLookup< T >::find ( vector3<>  v, Tag  tag = Tag(), const std::vector< Tag > *  tagArr = 0, TagEquality  tagEquality = std::equal_to<Tag>()  ) const

inline

Return index of a point within symmThresold of x, and string::npos if none found (Optionally also only return points whose tag matches the specified value)
