Structural group representation in the molecule.
A structural group is an entity in the molecule. Some of these entities has direct subclasses.
Some example use cases:
  • It can be an abbreviation of a molecule part represented as SuperatomSgroup.
  • A repeating unit in the molecule represented as RepeatingUnitSgroup.
  • Data assigned to a part of the molecule represented as DataSgroup .
  • A bond which has connection to multiple atom in the molecule is represented as multicenter sgroup type.
  • Components in the molecule can be represented as component sgroups.

See also the possible return values of getType() method which describes the possible sgroup types.
Some relevant functions in the molecule to handle these structural elements:
