Public Member Functions inherited from sc::SavableState SavableState & operator= (const SavableState &) void save_state (StateOut &) Save the state of the object as specified by the StateOut object. void save_object_state (StateOut &) This can be used for saving state when the exact type of the object is known for both the save and the restore. virtual void save_vbase_state (StateOut &) Save the virtual bases for the object. virtual void save_data_state (StateOut &) Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. Public Member Functions inherited from sc::DescribedClass DescribedClass (const DescribedClass &) DescribedClass & operator= (const DescribedClass &) ClassDesc * class_desc () const throw () This returns the unique pointer to the ClassDesc corresponding to the given type_info object. const char * class_name () const Return the name of the object's exact type. int class_version () const Return the version of the class. virtual void print (std::ostream &=ExEnv::out0()) const Print the object. Public Member Functions inherited from sc::RefCount int lock_ptr () const Lock this object. int unlock_ptr () const Unlock this object. void use_locks (bool inVal) start and stop using locks on this object refcount_t nreference () const Return the reference count. refcount_t reference () Increment the reference count and return the new count. refcount_t dereference () Decrement the reference count and return the new count. int managed () const void unmanage () Turn off the reference counting mechanism for this object. int managed () const Return 1 if the object is managed. Otherwise return 0. Public Member Functions inherited from sc::Identity Identifier identifier () Return the Identifier for this argument.

A vector, $given as the keyw{rd u, that is not colinear with either $r - or $- must be provided, where $r$, $and $are the positions of the first,} sec- ond, and third atoms, respectively. _ _ Usually, LinIPSimpleCo is used with a corresponding LinOPSimpleCo, which is given exactly the same u. r resignatin{ the three atoms as $a$, $b$, and $c$ and their cartesian posi- {ions as $r$,r$and $thr value of the coordinate, $heta_i$, is given by u { { { }b} = auc{r - r - }] = ac{- - }] heta_i = i - rccos ( }b}} } - rccos ( { _ _ _ Constructor & Destructor Documentation sc::LinIPSimpleCo::LinIPSimpleCo (const char * refr, int, int, int, const SCVector3 & u) This constructor takes a string containing a label, and three integers a, b, and d which give the indices of the atoms involved in the linear angle abc. The last argument, u, is a unit vector used to defined the direction in which distortion is measured. Atom numbering begins at atom 1, not atom 0. sc::LinIPSimpleCo::LinIPSimpleCo (const Ref< KeyVal > &) The KeyVal constructor. This calls the SimpleCo keyval constructor with an integer argument of 3.
