t_state Class Reference

#include <gromacs/mdtypes/state.h>

+ Collaboration diagram for t_state:

Description

The microstate of the system.

The global state will contain complete data for all used entries. The local state with domain decomposition will have partial entries for which stateEntryIsAtomProperty() is true. Some entries that are used in the global state might not be present in the local state.

Todo:
Move pure observables history to ObservablesHistory.

Public Member Functions

int numAtoms () const
 Returns the number of atoms represented by this state.
 
void changeNumAtoms (int numAtoms)
 Change the number of atoms represented by this state, allocating memory as needed.
 
bool hasEntry (StateEntry entry) const
 Returns whether entry entry is present.
 
void addEntry (StateEntry entry)
 Set entry entry to present, resizes corresponding vector to numAtoms() when relevant.
