Detailed Description

Date Reviewed:: before2004/08/25

Vector objects are one-dimensional specializations (e.g., more convenient and efficient indexing) of the general Array class. You might also want to look at the Array documentation to see inherited functionality.

Generally the member functions of Array are also available in Vector versions which take an integer where the array needs an IPosition. Since the Vector is one-dimensional, the IPositions are overkill, although you may use those versions if you want to.

Vector<int> vi(100); // Vector 100 elements long.

vi.resize(50); // Now only 50 long.

Slices may be taken with the Slice class. To take a slice, one "indexes" with Slice(start, length, inc) where end and inc are optional.

Vector<float> vf(100);
//..\.
vf(Slice(0,50,2)) = vf(Slice(1,50,2));  // Copy values from odd onto even
Vector<float> firstHalf, secondHalf;
firstHalf.reference(vf(Slice(0,50)));
secondHalf.reference(vf(Slice(50,50)));
// Now we have aliases for two slices into the Vector

Element-by-element arithmetic and logical operations are available (in aips/ArrayMath.h and aips/ArrayLogical.h) as well as dot and cross products (in aips/MatrixMath.h).

A Vector can be constructed from an STL vector. The reverse operation (Array::tovector()) can construct an STL vector from any Array.
Tip: To create any other STL container from an Array (or the reverse), always create from/to a vector, and use the range constructor to create from/to others (like set, list, deque);

As with the Arrays, if the preprocessor symbol AIPS_DEBUG is defined at compile time invariants will be checked on entry to most member functions. Additionally, if AIPS_ARRAY_INDEX_CHECK is defined index operations will be bounds-checked. Neither of these should be defined for production code.

casacore::Vector< T, Alloc >::Vector	(	const IPosition &	Length,
		typename Array< T, Alloc >::uninitializedType	,
		const Alloc &	allocator = `Alloc()`
	)

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector	(	const std::vector< T > &	other,
		long long	nr
	)

Create a Vector from the given std::vector "other." Make it length "nr" and copy over that many elements.

This used to take a 'Block'

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector	(	const std::vector< T > &	other,
		const Alloc &	allocator = `Alloc()`
	)

explicit

Create a Vector of length other.size() and copy over its values.

This used to take a 'Block'

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector ( std::initializer_list< T > list )

Create a Vector from an initializer list.

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector ( const Vector< T, Alloc > & other )

Create a reference to other.

noexcept

Move.

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector ( const Array< T, Alloc > & other )

Create a reference to the other array.

It is always possible if the array has zero or one axes. If it has > 1 axes, it is only possible if the array has at most one axis with length > 1. In that case the degenerated axes are removed.

template<typename T, typename Alloc = std::allocator<T>>

casacore::Vector< T, Alloc >::Vector	(	const IPosition &	shape,
		T *	storage,
		StorageInitPolicy	policy = `COPY`
	)

Create an Vector of a given shape from a pointer.

casacore::Vector< T, Alloc >::Vector	(	const IPosition &	shape,

Create an Vector of a given shape from a pointer.

Because the pointer is const, a copy is always made.

explicit

Create a Vector from an STL vector (see tovector() in Array for the reverse operation).

Tip: Both this constructor and the tovector() are defined in Vector2;cc;
It does implicit promotion/demotion of the type U if different from T.

template<typename T, typename Alloc = std::allocator<T>>

template<typename Iterator >

casacore::Vector< T, Alloc >::Vector	(	Iterator	first,
		size_t	size,
		int	dummy
	)

Create a Vector from a container iterator and its length.

Note: The length is used instead of last, because the distance function needed to calculate the length can be expensive;
A third dummy argument is unfortunately needed to avoid ambiguity with another Vector constructor (taking two uInts);

template<typename T, typename Alloc = std::allocator<T>>

template<typename InputIterator >

casacore::Vector< T, Alloc >::Vector	(	InputIterator	startIter,
		InputIterator	endIter,
		const Alloc &	allocator,

Remove the degenerate axes from other and store result in this vector.

An exception is thrown if removing degenerate axes does not result in a vector.

virtual size_t casacore::Vector< T, Alloc >::fixedDimensionality ( ) const

inlinefinaloverrideprotectedvirtual

Subclasses can return their dimensionality.

The Array class will make sure that whenever it is resized, the dimensionality is checked. Array's constructors do not check the dimensionality, because the subclass hasn't been created yet at that point. Subclasses should therefore make sure to call the constructors appropriately. For classes that return 0, any resize will be allowed.

Vector<T, Alloc> casacore::Vector< T, Alloc >::operator() ( const Slice & slice )

Take a slice of this vector.

Slices are always indexed starting at zero. This uses reference semantics, i.e. changing a value in the slice changes the original.

Vector<double> vd(100);
//..\.
vd(Slice(0,10)) = -1.0; // First 10 elements of vd set to -1

The array is masked by the input MaskedLogicalArray.

The mask is effectively the AND of the internal LogicalArray and the internal mask of the MaskedLogicalArray. The MaskedLogicalArray must conform to the array.

Convert a Vector to a Block, resizing the block and copying values.

This is done this way to avoid having the simpler Block class containing dependencies on the Vector class. void toBlock(Block<T> &other) const;

Single-pixel addressing. If AIPS_ARRAY_INDEX_CHECK is defined, bounds checking is performed (not for [])..
