Detailed Description

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

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

◆ Storage() [1/9]

template<typename T>

casacore::arrays_internal::Storage< T >::Storage ( )

inline

Construct an empty Storage.

◆ Storage() [2/9]

template<typename T>

casacore::arrays_internal::Storage< T >::Storage ( std::size_t n )

inline

Construct Storage with a given size.

The elements will be default constructed

◆ Storage() [3/9]

template<typename T>

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

inline

Construct Storage with a given size.

The elements will be copy constructed from the given value

Definition at line 27 of file Storage.h.

◆ Storage() [4/9]

template<typename T>

template<typename InputIterator>

casacore::arrays_internal::Storage< T >::Storage	(	InputIterator	startIter,
		InputIterator	endIter )

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

◆ construct() [1/2]

template<typename T>

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

These methods allocate the storage and construct the elements.
