Constructor & Destructor Documentation

template<typename T >

ebl::bstate_idx< T >::bstate_idx

(

)

Constructs a bstate_idx of order 0.

constructors from specific dimensions

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	intg	n,
		bstate_idx< T > &	fs
	)

This constructor initializes each buffer to the same order as 'ms.x' but sets all dimensions to 'n'.

template<typename T>

ebl::bstate_idx< T >::bstate_idx

(

parameter< T, bstate_idx< T > > *

st

)

constructors from specific dimensions using a bparameter Constructs a bstate_idx of order 0, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	parameter< T, bstate_idx< T > > *	st,
		intg	s0
	)

Constructs a bstate_idx of order 1, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	parameter< T, bstate_idx< T > > *	st,
		intg	s0,
		intg	s1
	)

Constructs a bstate_idx of order 2, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	parameter< T, bstate_idx< T > > *	st,
		intg	s0,
		intg	s1,
		intg	s2
	)

Constructs a bstate_idx of order 3, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	parameter< T, bstate_idx< T > > *	st,
		intg	s0,
		intg	s1,
		intg	s2,
		intg	s3,
		intg	s4 = -1,
		intg	s5 = -1,
		intg	s6 = -1,
		intg	s7 = -1
	)

Constructs a bstate_idx of order up to 8, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	parameter< T, bstate_idx< T > > *	st,
		const idxdim &	d
	)

Constructs a bstate_idx using the order and dimensions contained in passed idxdim d, by appending the bstate_idx into the same Srg as the bparameter passed as argument. This is useful for allocating multiple bstate_idx inside a bparameter. If st is null, it is just ignore and behaves as regular constructor.

template<typename T>

ebl::bstate_idx< T >::bstate_idx	(	const idx< T > &	x,
		const idx< T > &	dx
	)

constructors from other bstate_idx Constructs a bstate_idx from a bstate_idx's 3 internal idx Note: the data pointed to by idxs is not copied, we only create new idx pointing to the same data.
