Constructor & Destructor Documentation

BALL::SnapShot::SnapShot ( )

The default constructor. It creates an empty SnapShot object.

BALL::SnapShot::SnapShot ( const SnapShot & snapshot )

Copy constructor.

virtual BALL::SnapShot::~SnapShot ( )

virtual

The destructor.

Member Function Documentation

void BALL::SnapShot::applySnapShot ( System & system ) const

Apply the data contained in a SnapShot to a System. Copy all available data to the system. Note that some trajectory file formats do not contain all this information and vectors might be zero or even worse undefined when read SnapShots are read from such a file.

Parameters

system the System which will be manipulated

virtual void BALL::SnapShot::clear ( )

virtual

Clear method.

const ::std::vector<Vector3>& BALL::SnapShot::getAtomForces ( ) const

Get all atom forces.

void BALL::SnapShot::getAtomForces ( const System & system ) throw (Exception::OutOfMemory)

Read all atom forces from a System and store them in this instance of SnapShot.

Parameters

system the System from which data will be read

const ::std::vector<Vector3>& BALL::SnapShot::getAtomPositions ( ) const

Get the vector containing the atom postions.

void BALL::SnapShot::getAtomPositions ( const System & system ) throw (Exception::OutOfMemory)

Read all atom positions from a System and store them in this instance of SnapShot.

Parameters

system the System from which data will be read

const ::std::vector<Vector3>& BALL::SnapShot::getAtomVelocities ( ) const

Get the vector containing the atom velocitites.

void BALL::SnapShot::getAtomVelocities ( const System & system ) throw (Exception::OutOfMemory)

Read all atom velocities from a System and store them in this instance of SnapShot.

Parameters

system the System from which data will be read

Size BALL::SnapShot::getIndex ( ) const

Get the index of this instance.

DoubleReal BALL::SnapShot::getKineticEnergy ( ) const

Get the value for the kinetic energy of this snapshot's system.

Size BALL::SnapShot::getNumberOfAtoms ( ) const

Get the number of atoms that are covered by this snapshot.

DoubleReal BALL::SnapShot::getPotentialEnergy ( ) const

Get the value for the potential energy of this snapshot's system.
