All Implemented Interfaces:

StructureChecker, chemaxon.license.Licensable, PropertyChangeListener, Cloneable, EventListener

@PublicApi
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 ).

Since:

Marvin 5.3

Method Details

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)

Description copied from class: ComponentChecker

Checks if the component with index i has problem

Specified by:

check in class ComponentChecker<MolAtom>

Parameters:

molecule - is a Molecule instance

atom - the current component to check

Returns:

true if the component has problem, false otherwise

expandMolecule

protected Molecule expandMolecule(Molecule molecule,
 Map<MolAtom,MolAtom> atomMap,
 Map<MolBond,MolBond> bondMap)

Description copied from class: AbstractStructureChecker

Returns the original molecule if no groups to expand, or the clone of the original molecule with expanded groups.

Overrides:

expandMolecule in class AbstractStructureChecker

Parameters:

molecule - the molecule to check

Returns:

the original molecule, or a clone with expanded sgroups
