Detailed Description

Predicate class for atoms bearing a certain number of aromatic bonds.

Arguments of this class are required to consist of an relational operator and a number between 1 and 8. The default is ">0" which means that the atom under siege has to bear at least one aromatic bond to make this predicate's operator () () return true.

A bond is defined as aromatic if it has the property Bond::IS_AROMATIC set, or if its bond order equals Bond::ORDER__AROMATIC.
