Detailed Description

template<typename T, typename Alloc>
class casacore::arrays_internal::Storage< T, Alloc >

This class emplements a static (but run-time) sized array.

It is used in the Array class, and is necessary because std::vector specializes for bool. It holds the same functionality as a normal array, and enables allocation through different allocators similar to std::vector.

Constructor & Destructor Documentation

template<typename T , typename Alloc >

casacore::arrays_internal::Storage< T, Alloc >::Storage ( const Alloc & allocator )

inline

Construct an empty Storage.

template<typename T , typename Alloc >

casacore::arrays_internal::Storage< T, Alloc >::Storage	(	std::size_t	n,
		const Alloc &	allocator
	)

inline

Construct Storage with a given size.

The elements will be default constructed

template<typename T , typename Alloc >

casacore::arrays_internal::Storage< T, Alloc >::Storage	(	std::size_t	n,
		const T &	val,
		const Alloc &	allocator
	)

inline

Construct Storage with a given size.

The elements will be copy constructed from the given value

template<typename T , typename Alloc >

template<typename InputIterator >

casacore::arrays_internal::Storage< T, Alloc >::Storage	(	InputIterator	startIter,
		InputIterator	endIter,
		const Alloc &	allocator
	)

inline

Construct Storage from a range.

The elements will be copy constructed from the given values. Note that this constructor can be chosen over of Storage(std::size_t, const T&, const Alloc) when T=size_t. Therefore, this constructor forwards to the appropriate constructor based on whether T is an integral.

Member Function Documentation

template<typename T , typename Alloc >

T* casacore::arrays_internal::Storage< T, Alloc >::construct ( size_t n )

inlineprivate

These methods allocate the storage and construct the elements.

When any element constructor throws, the already constructed elements are destructed in reverse and the allocated storage is deallocated.
