Constructor & Destructor Documentation

BALL::RingAnalyser::RingAnalyser

(

)

Default-Constructor.

virtual BALL::RingAnalyser::~RingAnalyser ( )

virtual

Destructor.

Member Function Documentation

bool BALL::RingAnalyser::assignRTD_ ( std::list< Position > &  trial_system )

protected

interface for a Ring Template Database (RTD), no functionality yet

Returns

always returns false by now

void BALL::RingAnalyser::clear

(

)

Clears the datastructures. NOTE: The options remain! Use setDefaultOptions() to clear the options.

void BALL::RingAnalyser::clusterRings_ ( )

protected

performs an agglomerative clustering of single rings to ringsystems

void BALL::RingAnalyser::findSharedBonds_ ( )

protected

Find the bonds shared between rings in the sssr Precondition: the rings must be sorted such that a_i, a_i+1 share a bond (and a_size-1, a_0)

virtual bool BALL::RingAnalyser::finish ( )

virtual

Processor method which is called after the operator()-call.

Reimplemented from BALL::UnaryProcessor< AtomContainer >.

Size BALL::RingAnalyser::getNumberOfRingSystems

(

)

Return the number of ring systems.

std::vector<Position> BALL::RingAnalyser::getPeelingOrder

(

Position

i

)

Returns the peeling order for the i-th ring system.

std::vector<Ring> BALL::RingAnalyser::getRingSystem

(

Position

i

)

Returns the i-th ring system.

bool BALL::RingAnalyser::isCentralRing_ ( std::list< Position >::iterator  ring, std::list< Position > &  unassigned_rings  )

protected

bool BALL::RingAnalyser::isInRing	(	const Atom *	atom,
		std::vector< Atom * > const &	ring
	)		const

helper-function; determines, whether an atom is part of a certain ring

Parameters

atom	the atom
ring	the ring

Returns

true, if the atom is part of the ring, otherwise returns false

bool BALL::RingAnalyser::isInRingSystem	(	const Atom *	atom,
		Index	i
	)		const

helper-function; determines, whether an atom is part of a certain ring

Parameters

atom	the atom
i	the index of the ring system to test

Returns

true, if the atom is part of the ring system, otherwise returns false

virtual Processor::Result BALL::RingAnalyser::operator() ( AtomContainer &  ac )

virtual

Operator () for the processor

Parameters

ac	the AtomContainer to which the processor is applied.

Reimplemented from BALL::UnaryProcessor< AtomContainer >.

bool BALL::RingAnalyser::peelNextRing_ ( std::list< Position > &  unassigned_rings, bool  peel_fused = false  )

protected

void BALL::RingAnalyser::peelRings_ ( )

protected

performs an analysis of the structure of a ringsystem

void BALL::RingAnalyser::sequenceRing

(

std::vector< Atom * > &

ring

)

Puts the Atoms in the input ring into the correct order

After calling this function, for i, i+1 it holds that atom i is bonded to atom i+1, and that the last is bonded to the first entry

Parameters

ring	the input ring to sequence

virtual bool BALL::RingAnalyser::start ( )

virtual

Processor method which is called before the operator()-call.

Reimplemented from BALL::UnaryProcessor< AtomContainer >.
