Detailed Description

Class Group is an internal class used by class ReactionPath.

It represents some subset of the atoms of a molecule.

Definition at line 21 of file Group.h.

Member Function Documentation

void operator-= ( const Group other)
inline

Decrement the atom numbers by those in group 'other'.

Definition at line 53 of file Group.h.

References Group::validate().

void validate ( )

A group is 'valid' if all of its nonzero atom numbers have the same sign, either positive or negative.

This method checks for this, and if the group is not valid it sets m_sign to -999, and sets all atom numbers to zero.

Definition at line 25 of file Group.cpp.

Referenced by Group::operator-=().

bool valid ( ) const
inline

True if all non-zero atom numbers have the same sign.

Definition at line 109 of file Group.h.

int nAtoms ( ) const
inline

Number of atoms in the group (>= 0)

Definition at line 123 of file Group.h.

int nAtoms ( size_t  m) const
inline

Number of atoms of element m (positive or negative)
