Detailed Description

The class for representing atoms.

Notes:

many of the methods of Atom require that the Atom be associated with a molecule (an ROMol).
each Atom maintains a Dict of properties:
- Each property is keyed by name and can store an arbitrary type.
- Properties can be marked as calculated, in which case they will be cleared when the clearComputedProps() method is called.
- Because they have no impact upon chemistry, all property operations are const, this allows extra flexibility for clients who need to store extra data on Atom objects.
Atom objects are lazy about computing their explicit and implicit valence values. These will not be computed until their values are requested.

Chirality:

The chirality of an Atom is determined by two things:

its chiralTag
the input order of its bonds (see note below for handling of implicit Hs)

For tetrahedral coordination, the chiralTag tells you what direction you have to rotate to get from bond 2 to bond 3 while looking down bond 1. This is pretty much identical to the SMILES representation of chirality.

NOTE: if an atom has an implicit H, the bond to that H is considered to be at the end of the list of other bonds.

inverts our chiralTag, returns whether or not a change was made

◆ Match()

virtual bool RDKit::Atom::Match ( Atom const * what ) const

virtual

returns whether or not we match the argument

Notes: The general rule is that if a property on this atom has a non-default value, the property on the other atom must have the same value. The exception to this is H counts, which are ignored. These turns out to be impossible to handle generally, so rather than having odd and hard-to-explain exceptions, we ignore them entirely.

Here are the rules for atom-atom matching: | This | Other | Match | Reason | CCO | CCO | Yes | | CCO | CC[O-] | Yes | | CC[O-] | CCO | No | Charge | CC[O-] | CC[O-] | Yes | | CC[OH] | CC[O-] | Yes | | CC[OH] | CCOC | Yes | | CCO | CCOC | Yes | | CCC | CCC | Yes | | CCC | CC[14C] | Yes | | CC[14C] | CCC | No | Isotope | CC[14C] | CC[14C] | Yes | | C | OCO | Yes | | [CH] | OCO | Yes | | [CH2] | OCO | Yes | | [CH3] | OCO | No | Radical | C | O[CH2]O | Yes | | [CH2] | O[CH2]O | Yes |
