All Implemented Interfaces:

StructureChecker, chemaxon.license.Licensable, java.beans.PropertyChangeListener, java.lang.Cloneable, java.util.EventListener

public class OverlappingAtomsChecker
extends AtomChecker

OverlappingAtomsChecker detects atoms that are too close to each other.

This checker checks 2D structures only.

Two atoms considered as overlapping when their euclidean distance is less than the half of the ChemAxon standard bond length ( MolBond.CCLENGTH ).

Method Detail

check1

protected StructureCheckerResult check1(Molecule molecule)

Description copied from class: ComponentChecker

Iterates through the components and checks every component. If a component has error it is added to a List. After the iteration if no problem occurred the result is null otherwise the method creates a StructureCheckerResult containing the atoms and bonds of the problematic components.

Overrides:

check1 in class ComponentChecker<MolAtom>

Parameters:

molecule - the Molecule instance to be checked for problems

Returns:

a StructureCheckerResult which contains all the indices of the problematic components

check

protected boolean check(Molecule molecule,
                        MolAtom atom)

Examines if an atom is closer to another than the given distance limit.

Specified by:

check in class ComponentChecker<MolAtom>

Parameters:

atom - the index of atom in the molecule to check

molecule - is a Molecule instance

Returns:

true if the molecule contains overlapping atoms, otherwise false
