Detailed Description

template<typename T, std::size_t Cap>
class real::detail::static_vec< T, Cap >

Fixed-capacity vector backed by an inline array (no heap).

The subset of std::vector the Pike VM uses, for the static storage mode. Overflow cannot happen for the engine's own containers: static_storage sizes each one exactly via its measure pass, so the length_error guards are an unreachable structural safety net — kept deliberately, and never hit at run time (hence not covered by the runtime coverage report).

Template Parameters

T	Element type.
Cap	Inline capacity.

Member Function Documentation

assign()

template<typename T , std::size_t Cap>

constexpr void real::detail::static_vec< T, Cap >::assign ( std::size_t  count, const T &  value  )

inlineconstexpr

Resizes to count copies of value.

Parameters

[in]	count	Number of elements.
[in]	value	The value to fill with.

Exceptions

std::length_error

if count exceeds the capacity Cap.

Definition at line 122 of file storage.hpp.

back()

template<typename T , std::size_t Cap>

constexpr T & real::detail::static_vec< T, Cap >::back ( )

inlineconstexpr

Returns reference to the last element. Precondition: the vector is non-empty.

Definition at line 173 of file storage.hpp.

clear()

template<typename T , std::size_t Cap>

constexpr void real::detail::static_vec< T, Cap >::clear ( )

inlineconstexpr

Removes all elements (capacity unchanged).

Definition at line 111 of file storage.hpp.

empty()

template<typename T , std::size_t Cap>

constexpr bool real::detail::static_vec< T, Cap >::empty ( ) const

inlineconstexpr

Returns true if empty.

Definition at line 145 of file storage.hpp.

operator[]() [1/2]

template<typename T , std::size_t Cap>

constexpr T & real::detail::static_vec< T, Cap >::operator[] ( std::size_t  i )

inlineconstexpr

Returns reference to the element at i.

Parameters

[in]

i

Index.

Returns

Reference to the element at i.

Definition at line 155 of file storage.hpp.

operator[]() [2/2]

template<typename T , std::size_t Cap>

constexpr const T & real::detail::static_vec< T, Cap >::operator[] ( std::size_t  i ) const

inlineconstexpr

Returns const reference to the element at i.

Parameters

[in]

i

Index.

Returns

Const reference to the element at i.

Definition at line 165 of file storage.hpp.

pop_back()

template<typename T , std::size_t Cap>

constexpr void real::detail::static_vec< T, Cap >::pop_back ( )

inlineconstexpr

Removes the last element. Precondition: the vector is non-empty.

Definition at line 182 of file storage.hpp.

push_back()

template<typename T , std::size_t Cap>

constexpr void real::detail::static_vec< T, Cap >::push_back ( const T &  value )

inlineconstexpr

Appends value.

Parameters

[in]

value

The element to append.

Exceptions

std::length_error

if the capacity Cap is exceeded.

Definition at line 99 of file storage.hpp.

size()

template<typename T , std::size_t Cap>

constexpr std::size_t real::detail::static_vec< T, Cap >::size ( ) const

inlineconstexpr

Returns the number of elements.
