Constructor &eDestructor Documentation
sc::BendSimpleCo::BendSimpleCo (const char *, int, int, int)
This constructor takes a string containing a label, and three integers a, b, and c which
give the indices of the atoms involved in the angle abc. Atom numbering begins at atom 1,
not atom 0.
sc::BendSimpleCo::BendSimpleCo (const Ref< KeyVal > &)
The KeyVal constructor. This calls the SimpleCo keyval constructor with an integer
argument of 3.
