Package org.openscience.cdk.hash.stereo

Class GeometricDoubleBondEncoderFactory

java.lang.Object

org.openscience.cdk.hash.stereo.GeometricDoubleBondEncoderFactory

All Implemented Interfaces:

StereoEncoderFactory

public final class GeometricDoubleBondEncoderFactory
extends Object
implements StereoEncoderFactory

A stereo encoder factory encoding double bond configurations by 2D and 3D coordinates. This factory will attempt to encode all double bonds that meet the following conditions. Are not -N=N- bonds, non-cumulated, non-query and have each double bonded atom has at least one substituent. In future the encoding rules may be more strict or even configurable but currently they may be over zealous when encoding configurations with 3D coordinates.
This class is intended to be used with a the hash encoding classes and is easier used via the HashGeneratorMaker.
