virtual unsigned int GetImplicitHCount() const
Return the number of implicit hydrogens attached to atom. The default
value is zero. The ``implicit hydrogen count'' property may be set
using the OEAtomBase::SetImplicitHCount
method. Implicit hydrogen
counts may also be set on a molecule using the function
OEAssignImplicitHydrogens
. The implicit hydrogen count property
of an atom is a stored, not a computed, property. To calculate a
reasonable implicit hydrogen count for an atom from connectivity, use
the function OEDefaultImplicitHCount
.
To convert explicit hydrogens to implicit hydrogens, use the OEChem
function OESupressHydrogens
, and to convert implicit hydrogens
to explicit hydrogens, use the function OEAddExplicitHydrogens
.
