Constructor & Destructor Documentation

DisjointSet()

template<typename T = int64_t>

blender::DisjointSet< T >::DisjointSet ( const int64_t size )

inline

Create a new disjoint set with the given size. Initially, every element is in a separate set.

find_root()

template<typename T = int64_t>

T blender::DisjointSet< T >::find_root ( const T x )

inline

Find the element that represents the set containing x currently.

in_same_set()

template<typename T = int64_t>

bool blender::DisjointSet< T >::in_same_set ( const T x, const T y )

inline

Return true when x and y are in the same set.

join()

template<typename T = int64_t>

void blender::DisjointSet< T >::join ( const T x, const T y )

inline

Join the sets containing elements x and y. Nothing happens when they have been in the same set before.
