Member Function Documentation

gain()

template<typename T >

virtual T ogdf::steiner_tree::Save< T >::gain ( node  u, node  v, node  w  ) const

pure virtual

Returns the gain (sum of the save edges) of a node triple.

Parameters

u	First triple node
v	Second triple node
w	Third triple node

Returns

Sum of the save edges between the three nodes

Implemented in ogdf::steiner_tree::SaveEnum< T >, ogdf::steiner_tree::SaveStatic< T >, and ogdf::steiner_tree::SaveDynamic< T >.

saveEdge()

template<typename T >

virtual edge ogdf::steiner_tree::Save< T >::saveEdge ( node  u, node  v  ) const

pure virtual

Returns the save edge between two nodes.

Parameters

u	First node
v	Second node

Returns

The save edge

Implemented in ogdf::steiner_tree::SaveDynamic< T >, ogdf::steiner_tree::SaveEnum< T >, and ogdf::steiner_tree::SaveStatic< T >.

saveWeight()

template<typename T >

virtual T ogdf::steiner_tree::Save< T >::saveWeight ( node  u, node  v  ) const

pure virtual

Returns the weight of the save edge between two nodes.

Parameters

u	First node
v	Second node

Returns

The weight of the save edge

Implemented in ogdf::steiner_tree::SaveDynamic< T >, ogdf::steiner_tree::SaveEnum< T >, and ogdf::steiner_tree::SaveStatic< T >.

update()

template<typename T >

virtual void ogdf::steiner_tree::Save< T >::update ( const Triple< T > &  t )

pure virtual

Updates the weighted tree data structure given a contracted triple.

Parameters

t	The contracted triple

Implemented in ogdf::steiner_tree::SaveEnum< T >, ogdf::steiner_tree::SaveDynamic< T >, and ogdf::steiner_tree::SaveStatic< T >.
