Class to hold the component energies between pairs of residues. Each node represents a residue in its corresponding structure. Each edge in the graph holds a two-body energy map representing the unweighted components of the energy function for those terms with non-zero weight. The EnergyGraph may be accessed from the pose's Energies object, but at a price of an extra score evaluation. This second score evaluation may be avoided if you use the ScoreFunction::score_components( pose ) method. More...

Detailed Description

Class to hold the component energies between pairs of residues. Each node represents a residue in its corresponding structure. Each edge in the graph holds a two-body energy map representing the unweighted components of the energy function for those terms with non-zero weight. The EnergyGraph may be accessed from the pose's Energies object, but at a price of an extra score evaluation. This second score evaluation may be avoided if you use the ScoreFunction::score_components( pose ) method.

core::scoring::EnergyGraph::EnergyGraph ( Size num_nodes )

This does not call the base class parent( Size ) constructor since that produces calls to the polymorphic function create_new_node() and polymorphism does not work during constructor intialization.

Referenced by count_static_memory().

core::scoring::EnergyGraph::EnergyGraph ( EnergyGraph const & src )

Notice that this does not call the parent( src ) copy constructor. This is because the copy constructor relies on polymorphic functions which are unavailable during the Graph constructor. Instead, this function waits until parent construction is complete, and relies on the assigmnent operator.

bool core::scoring::EnergyGraph::active_score_types ( ScoreTypes const & active )

Set the active score types, and return true if the new score types are the same as the old score types and the graph state is still good. Returns false if the score types have changed, indicating that the graph has dropped all of its edges;.

The array pool only needs to be resized if the number of active score types has changed; it doesn't have to be resized if the actual active types have changed but the number of active score types has remained constant. However, if either the number or the identity of the active score types have changed, then all old edges in the EnergyGraph should be dropped. The input array "active" must be sorted.
