Constructor & Destructor Documentation

BALL::RingFinder::RingFinder

(

)

Default constructor.

BALL::RingFinder::RingFinder

(

Size

n

)

Detailed constructor. Initialize this instance with the size of the ring we want to find. Default setting is 0 which means that any ring size will match.

virtual BALL::RingFinder::~RingFinder

(

)

[virtual]

Destructor.

Member Function Documentation

bool BALL::RingFinder::dfs	(	const Atom &	atom,
		const Size	limit
	)

Depth first search for finding rings.

const std::vector<const Atom*>& BALL::RingFinder::getRingAtoms

(

)

const

Return the vector of ring atoms.

const HashSet<const Bond*>& BALL::RingFinder::getVisitedBonds

(

)

const

Return the hashset containing all visited bonds.

bool BALL::RingFinder::operator()

(

const Atom &

atom

)

Return true, if atom is in a ring.

void BALL::RingFinder::setRingSize

(

Size

n

)

Set the ring size we want to find. Ring sizes below 3 will always return false, except if the size is set to 0, then any ring size will match.
