Enumeration Type Documentation

enum Canon::AtomColors

used in traversals of the molecule

Enumerator:

WHITE_NODE
GREY_NODE	not visited
BLACK_NODE	visited, but not finished

Definition at line 20 of file Canon.h.

enum Canon::MolStackTypes

used to indicate types of entries in the molecular stack:

Enumerator:

MOL_STACK_ATOM	an Atom
MOL_STACK_BOND	a Bond
MOL_STACK_RING	a ring closure
MOL_STACK_BRANCH_OPEN	beginning of a branch
MOL_STACK_BRANCH_CLOSE	end of a branch

Function Documentation

int Canon::_possibleComp	(	const PossibleType &	arg1,
		const PossibleType &	arg2
	)

compare two PossibleTypes

void Canon::canonicalizeFragment	(	RDKit::ROMol &	mol,
		int	atomIdx,
		std::vector< AtomColors > &	colors,
		std::vector< int > &	ranks,
		MolStack &	molStack
	)

constructs the canonical traversal order for a molecular fragment

Parameters:

	mol	the ROMol we're working on
	atomIdx	the index of the atom to start the traversal from
	colors	the traversal status of each atom in mol
	ranks	the assigned rank of each atom in mol
	molStack	the current traversal stack (used to return the results)

Notes

• mol will, in general, be modified by this operation as bond directions and the like are changed to fit the canonical traversal order

PossibleType Canon::makePossible	(	int	rank,
		int	atomIdx,
		RDKit::Bond *	bond
	)

returns a PossibleType
