Constructor & Destructor Documentation

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

lite::array< signature_, traits_type_, rep_ >::array

(

)

Default constructs the array.

All non-constant dimension sizes are set to 0. The content of the array (in cases it has a fixed size and therefore not initially empty) will be left uninitialized unless the elements of the array have a user-defined type that has its own default constructor. A reference array will be initialized to a null reference.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

lite::array< signature_, traits_type_, rep_ >::array

(

const array< signature_, traits_type_, rep_ > &

other

)

Initializes the array to a copy of the other array.

Remarks:

In case of a reference array, only the reference is copied.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

template<typename other_rep_ >

lite::array< signature_, traits_type_, rep_ >::array

(

const array< signature_, traits_type_, other_rep_ > &

other

)

[inline]

Initializes the array to a copy of the other array. The other array could have a different representation type.

Remarks:

In case of a reference array, only the reference is copied. The other array could have a different representation type with an iterator type that is convertible to the current reference array's iterator_type.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

lite::array< signature_, traits_type_, rep_ >::array	(	int	n0,
			...,
		int	nN
	)			[explicit]

Constructs an array with the given dimension sizes.

All non-constant dimension sizes are set to their corresponding supplied value from a0 to aN. The arguments corresponding to fixed-size dimensions are ignored. The array is then allocated. The content of the array will be left uninitialized unless the elements of the array have a user-defined type that has its own default constructor.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

lite::array< signature_, traits_type_, rep_ >::array

(

const size_type &

size

)

[explicit]

Constructs an array with the given dimension sizes.

The array is then allocated. The content of the array will be left uninitialized unless the elements of the array have a user-defined type that has its own default constructor.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

lite::array< signature_, traits_type_, rep_ >::array	(	const value_type &	a0,
			...,
		const value_type &	aT
	)

Constructs an array using the supplied values.

Remarks:

This constructor is only available for vectors (1D arrays) that use the internal representation (Internal Representation) and have a fixed size of at most LITE_ARRAY_MAX_VECTOR_ARGS .

Example

            array<double[2]> a(2.3, 4.5);
            array<double[3]> a(2.3, 4.5, 4.6);
            array<double[9]> a(1, 2, ..., 9); // error: more than LITE_ARRAY_MAX_VECTOR_ARGS number of args.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

template<typename arg_type0_ , ... , typename arg_typeK_ >

lite::array< signature_, traits_type_, rep_ >::array	(	const arg_type0_ &	arg0,
			...,
		const arg_typeK_ &	argK,
		const size_type &	sz
	)			[inline]

Constructs a reference array by passing the arg0 to argK to the constructor of the iterator which is maintained internally and using the size sz .

Remarks:

This constructor is only available in reference arrays (see Reference Representation). Also, K should be less than LITE_ARRAY_MAX_ITERATOR_ARGS. In other words, this constructor can take at most LITE_ARRAY_MAX_ITERATOR_ARGS arguments to be passed to the constructor of the iterator. This constructor is used internally by almost all array operations that return a reference array.

template<typename signature_, typename traits_type_ = default_array_traits, typename rep_ = typename traits_type_::template representation_type<signature_>::type>

template<typename other_iterator_type_ , typename other_size_type_ , typename transform_type_ >

lite::array< signature_, traits_type_, rep_ >::array	(	const other_iterator_type_ &	it,
		const other_size_type_ &	sz,
		const transform_type_ &	trans
	)			[inline]

Constructs a reference array by applying the transform trans to the iterator it and size object sz.

Remarks:

This constructor is only available in reference arrays (see Reference Representation) and is used internally by operator[] of array classes to construct a reference array to be returned as the result of applying a transform.
