Detailed Description

template<class T>
struct hr::walker< T >

the walker structure is used for walking on surfaces defined via connection_table.

Member Function Documentation

operator+=() [1/5]

template<class T >

walker<T>& hr::walker< T >::operator+= ( int  i )

inline

spin by i to the left (or right, when mirrored

operator-=()

template<class T >

walker<T>& hr::walker< T >::operator-= ( int  i )

inline

spin by i to the right (or left, when mirrored

operator+=() [2/5]

template<class T >

walker<T>& hr::walker< T >::operator+= ( wmirror_t  )

inline

add wmirror to mirror this walker

operator+=() [3/5]

template<class T >

walker<T>& hr::walker< T >::operator+= ( wstep_t  )

inline

add wstep to make a single step, after which we are facing the T we were originally on

operator+=() [4/5]

template<class T >

walker<T>& hr::walker< T >::operator+= ( rev_t  )

inline

add wrev to face the other direction, may be non-deterministic and use hrand

operator+=() [5/5]

template<class T >

walker<T>& hr::walker< T >::operator+= ( revstep_t  )

inline

adding revstep is equivalent to adding rev and step

peek()

template<class T >

T*& hr::walker< T >::peek ( )

inline

what T are we facing, without creating it

cpeek()

template<class T >

T* hr::walker< T >::cpeek ( )

inline

what T are we facing, with creating it

creates()

template<class T >

bool hr::walker< T >::creates ( )

inline

would we create a new T if we stepped forwards?

mirrorat()

template<class T >

walker<T> hr::walker< T >::mirrorat ( int  d )

inline

mirror this walker with respect to the d-th edge

Member Data Documentation

at

template<class T >

T* hr::walker< T >::at

where we are at

spin

template<class T >

int hr::walker< T >::spin

in which direction (edge) we are facing

mirrored

template<class T >

bool hr::walker< T >::mirrored

are we mirrored
