Class: VariableAtom

VariableAtom

new VariableAtom(id, coord2D, coord3D)

Represent an variable atom, In this type of atom, element/isotope can be one of a range. (such as atomlist in MDL CTAB).
Parameters:
Name Type Description
id String Id of this node.
coord2D Object The 2D coordinates of node, {x, y}, can be null.
coord3D Object The 3D coordinates of node, {x, y, z}, can be null.
Properties:
Name Type Description
allowedIsotopeIds Array Atom isotope may vary in this array.
disallowedIsotopeIds Array Atom isotope must not in the array. if Kekule.VariableAtom#allowedIsotopeIds is set, this property is ignored.
