Class ReactionContext

java.lang.Object
  chemaxon.jep.ChemContext
      chemaxon.jep.context.ReactionContext

All Implemented Interfaces:

chemaxon.marvin.util.CallbackIface, java.io.Serializable

public class ReactionContext
extends ChemContext

Expression evaluation context used by the chemaxon.reaction.Reactor to evaluate reaction conditions. Contains reaction context elements: reactants, products, map-to-atom correspondences for both sides. Provides function names for accessing context elements through the CallbackIface.

Since:

JChem 2.2, Marvin 5.1

callback

public java.lang.Object callback(java.lang.String method,
                                 java.lang.Object arg)

Implements CallbackIface. Returns null for unimplemented callbacks. Implemented callbacks:

method	arg	return value
"reactant"	reactant index (Integer, 0-based)	the reactant
"product"	product index (Integer, 0-based)	the ptoduct
"ratom"	atom map (Integer)	the reactant atom
"patom"	atom map (Integer)	the product atom

Specified by:

callback in interface chemaxon.marvin.util.CallbackIface

Overrides:

callback in class ChemContext

Parameters:

method - is the accessor method name

arg - is the accessor method argument (the JEP parameter stack as null, a single parameter object or a parameter object array depending on the number of parameters on the stack)

Returns:

the context element

setReactants
