Variable Documentation

CONSTRAINT_LIST

const unsigned int CDPL::Chem::ReactionMatchConstraint::CONSTRAINT_LIST = 0

Specifies a constraint which requires the target reaction to fulfill additional contraints specified by a Chem::MatchConstraintList object.

ATOM_MAPPING

const unsigned int CDPL::Chem::ReactionMatchConstraint::ATOM_MAPPING = 1

Specifies a constraint which requires the target reaction to match the reactant to product atom mapping of the query reaction.

COMPONENT_GROUPING

const unsigned int CDPL::Chem::ReactionMatchConstraint::COMPONENT_GROUPING = 2

Specifies a constraint which requires the target reaction to match any component level groupings defined by the query reaction.

Component level groupings specify whether the components of a query reaction have to be matched by a single target reaction component (intramolecular reaction) or by different components of the target (intermolecular reaction). Daylight SMARTS patterns [SMARTS] allow to specify component groupings by parentheses that enclose those components of the query which have to be part of the same target reaction component.
