bool operator()(const Feature &ftr1, const Feature &ftr2) const
Tests whether ftr1 and ftr2 satisfy the geometric halogen-bond criteria.
double getMinAXBAngle() const
Returns the currently configured minimum acceptor-halogen-bound-atom angle.
double getMaxAcceptorAngle() const
Returns the currently configured maximum deviation from the acceptor's preferred X-bonding direction.
double getMinAXDistance() const
Returns the currently configured minimum halogen-acceptor distance.
double getMaxAXDistance() const
Returns the currently configured maximum halogen-acceptor distance.
