Inheritance diagram for sc::OperatorDescr:

Public Member Functions
virtual unsigned int	num_particles () const =0
virtual int	perm_symm (unsigned int p) const =0
	Reports symmetry with respect to the permutation of function in bra with function in ket for particle p +1 corresponds to hermitian, -1 to antihermitian, 0 to nonhermitian.
virtual int	perm_symm (unsigned int i, unsigned int j) const =0
	Reports symmetry with respect to permutation of particles i and j in bra, or ket.
Public Member Functions inherited from sc::RefCount
size_t	identifier () const
	Return the unique identifier for this object that can be compared for different objects of different types.
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
	Return 1 if the object is managed. Otherwise return 0.

Detailed Description

For an operator (e.g.

<ij|1/r12|kl> ) OperatorDescr gives basic properties with respect to permutations, etc.
