Detailed Description

template<class Element_t, class Array_t>
requires requires
class mysql::abi_helpers::detail::Array_base< Element_t, Array_t >

Base class for specific implementations of standard-layout classes for arrays.

This stores the length and the array, and exposes iterators, index operators and member functions to query size/emptiness.

Template Parameters

Element_t	The type of each element.
Array_t	The type of the array, for example Element_t * or Element_t[7].

Member Function Documentation

begin() [1/2]

template<class Element_t , class Array_t >

Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::begin ( )

inline

Returns

Iterator to the beginning (non-const).

Actually, just the raw pointer. This is a contiguous iterator.

begin() [2/2]

template<class Element_t , class Array_t >

const Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::begin ( ) const

inline

Returns

Iterator to the beginning (const).

cbegin()

template<class Element_t , class Array_t >

const Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::cbegin ( ) const

inline

Returns

Iterator to the beginning (const).

cend()

template<class Element_t , class Array_t >

const Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::cend ( ) const

inline

Returns

Iterator to the end (const).

data() [1/2]

template<class Element_t , class Array_t >

Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::data ( )

inline

Returns

Pointer to the array (non-const, equal to begin()).

data() [2/2]

template<class Element_t , class Array_t >

const Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::data ( ) const

inline

Returns

Pointer to the array (const, equal to cbegin()).

empty()

template<class Element_t , class Array_t >

bool mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::empty ( ) const

inline

Returns

true if there are no elements, false if there are any.

end() [1/2]

template<class Element_t , class Array_t >

Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::end ( )

inline

Returns

Iterator to the end (non-const).

Actually, just the raw pointer. This is a contiguous iterator.

end() [2/2]

template<class Element_t , class Array_t >

const Element_t * mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::end ( ) const

inline

Returns

Iterator to the end (const).

operator bool()

template<class Element_t , class Array_t >

mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::operator bool ( ) const

inline

Returns

true if there are any elements, false if there are none.

operator[]() [1/2]

template<class Element_t , class Array_t >

Element_t & mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::operator[] ( std::size_t  index )

inline

Index operator (non-const).

Parameters

index

Array index.

Returns

Non-const reference to element at the given index.

operator[]() [2/2]

template<class Element_t , class Array_t >

const Element_t & mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::operator[] ( std::size_t  index ) const

inline

Index operator (const).

Parameters

index

Array index.

Returns

Const reference to element at the given index.

size()

template<class Element_t , class Array_t >

std::size_t mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::size ( ) const

inline

Returns

Number of elements.

ssize()

template<class Element_t , class Array_t >

std::ptrdiff_t mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::ssize ( ) const

inline

Returns

Number of elements (signed).

Member Data Documentation

m_data

template<class Element_t , class Array_t >

Array_t mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::m_data

protected

Array data.

m_size

template<class Element_t , class Array_t >

int32_t mysql::abi_helpers::detail::Array_base< Element_t, Array_t >::m_size

protected

Number of elements in the array.

We keep it as 32 bits, so that small arrays may fit in 64 bits.
