Constructor & Destructor Documentation

◆ EmbeddedFrag() [1/5]

RDDepict::EmbeddedFrag::EmbeddedFrag ( )

inline

Default constructor.

Definition at line 153 of file EmbeddedFrag.h.

◆ EmbeddedFrag() [2/5]

RDDepict::EmbeddedFrag::EmbeddedFrag	(	unsigned int	aid,
		const RDKit::ROMol *	mol )

Initializer from a single atom id.

A single Embedded Atom with this atom ID is added and placed at the origin

◆ EmbeddedFrag() [3/5]

RDDepict::EmbeddedFrag::EmbeddedFrag	(	const RDKit::ROMol *	mol,
		const RDGeom::INT_POINT2D_MAP &	coordMap )

Constructor when the coordinates have been specified for a set of atoms.

This simply initialized a set of EmbeddedAtom to have the same coordinates as the one's specified. No testing is done to verify any kind of correctness. Also this fragment is less ready (to expand and add new neighbors) than when using other constructors. This is because:

the user may have specified coords for only a part of the atoms in a fused ring systems in which case we need to find these atoms and merge these ring systems to this fragment
The atoms are not yet aware of their neighbor (what is left to add etc.) this again depends on atoms properly so that new neighbors can be added to them

◆ EmbeddedFrag() [4/5]

RDDepict::EmbeddedFrag::EmbeddedFrag	(	const RDKit::ROMol *	mol,
		const RDKit::VECT_INT_VECT &	fusedRings,
		bool	useRingTemplates )

Initializer from a set of fused rings.

ARGUMENTS:

Parameters

mol	the molecule of interest
fusedRings	a vector of rings, each ring is a list of atom ids
useRingTemplates	whether to use ring system templates for generating initial coordinates

◆ EmbeddedFrag() [5/5]

RDDepict::EmbeddedFrag::EmbeddedFrag ( const RDKit::Bond * dblBond )

explicit

Initializer for a cis/trans system using the double bond.

ARGUMENTS:

Parameters

dblBond the double bond that is involved in the cis/trans configuration
