Constructor & Destructor Documentation

DisjointSets()

template<typename T >

inviwo::DisjointSets< T >::DisjointSets ( T  size )

inlineexplicit

Construct size disjoint sets with 1 member in each set.

Member Function Documentation

cardinality()

template<typename T >

T inviwo::DisjointSets< T >::cardinality ( T  x )

inline

Returns cardinality of the set for element x Requires x to be positive and less than size.

find()

template<typename T >

T inviwo::DisjointSets< T >::find ( T  x )

inline

Returns name of the set for element x i.e. return root of tree for element x Requires x to be positive and less than size.

join()

template<typename T >

bool inviwo::DisjointSets< T >::join ( T  r, T  s  )

inline

Join the sets of element r and s. Requires r and s to be positive and less than size. Return true it the sets were joined or false if r and s already were in the same set.

size()

template<typename T >

std::size_t inviwo::DisjointSets< T >::size ( )

inline

Returns the total number of elements in all sets
