All Implemented Interfaces:

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

public class OverlappingBondsChecker
extends BondChecker

OverlappingBondsChecker detects bonds that are too close to each other.

This checker checks two dimensional structures only.

Two bonds considered as overlapping when they crossing each other, or their distance is smaller then the 80% of the standard ChemAxon bond length ( MolBond.CCLENGTH ). Here distance means the distance of two line segments in euclidean space.

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<MolBond>

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,
                        MolBond bond)

Detects bond of the molecule is crossing another bond or closer than the limit distance.

Specified by:

check in class ComponentChecker<MolBond>

Parameters:

bond - the index of the bond (MolBond instance) in the molecule to check

molecule - is a Molecule instance

Returns:

true if the molecule contains crossing bonds, false otherwise
