org.openscience.cdk.silent.Reaction

All Implemented Interfaces:

Serializable, Cloneable, ICDKObject, IChemObject, IReaction

public class Reaction
extends ChemObject
implements Serializable, IReaction, Cloneable

Represents the idea of a chemical reaction. The reaction consists of a set of reactants and a set of products.

The class mostly represents abstract reactions, such as 2D diagrams, and is not intended to represent reaction trajectories. Such can better be represented with a ChemSequence.
