Coulomb::meTable< T >

Look-up table for matrix elements. Note: does not assume any symmetry: (a,b) is stored independantly of (b,a). In general, maps a pair of DiracSpinors to a single value (of any type, T). More...

Public Member Functions
auto	operator-> ()
void	add (const DiracSpinor &a, const DiracSpinor &b, T value)
	Adds new element to table. If already exists, does nothing (does not update)
void	add (DiracSpinor::Index a, DiracSpinor::Index b, T value)
	Adds new element to table. If already exists, does nothing (does not update)
void	add (const meTable< T > &other)
	Adds elements from one Table into another (by copy)
void	update (const DiracSpinor &a, const DiracSpinor &b, T value)
	Updates given element in table. If element not yet present, adds it.
void	update (DiracSpinor::Index a, DiracSpinor::Index b, T value)
	Updates given element in table. If element not yet present, adds it.
bool	contains (const DiracSpinor &a, const DiracSpinor &b) const
	Checks if given element is in the table.
bool	contains (DiracSpinor::Index a, DiracSpinor::Index b) const
	Checks if given element is in the table.
const T *	get (const DiracSpinor &a, const DiracSpinor &b) const
	Gets pointer to const requested element. If element not present, returns nullptr.
const T *	get (DiracSpinor::Index a, DiracSpinor::Index b) const
	Gets pointer to const requested element. If element not present, returns nullptr.
T *	get (const DiracSpinor &a, const DiracSpinor &b)
	Gets pointer to mutable requested element. If element not present, returns nullptr.
T *	get (DiracSpinor::Index a, DiracSpinor::Index b)
	Gets pointer to mutable requested element. If element not present, returns nullptr.
T	getv (const DiracSpinor &a, const DiracSpinor &b) const
	Gets value of requested element. If element not present, returns zero (or default constructed T)
T	getv (DiracSpinor::Index a, DiracSpinor::Index b) const
	Gets value of requested element. If element not present, returns zero (or default constructed T)
const T *	get (const std::string &a, const std::string &b) const
	Gets pointer to const requested element. If element not present, returns nullptr. Overload for strings (parses symbol)
auto	begin ()
	Provide iterators.
auto	end ()
auto	cbegin () const
auto	cend () const

Detailed Description

template<typename T = double>
class Coulomb::meTable< T >

Look-up table for matrix elements. Note: does not assume any symmetry: (a,b) is stored independantly of (b,a). In general, maps a pair of DiracSpinors to a single value (of any type, T).
