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
uFirst triple node
vSecond triple node
wThird 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
uFirst node
vSecond 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
uFirst node
vSecond 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
tThe contracted triple

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