slint::SharedVector Struct

template <typename T>
struct SharedVector;

C++

#include <slint.h>

C++

SharedVector is a vector template class similar to std::vector ↗ that’s primarily used for passing data in and out of the Slint run-time library. It uses implicit-sharing to make creating copies cheap. Only when a function changes the vector’s data, a copy is is made.

Public Functions

SharedVector

slint::SharedVector< T >::SharedVector()

Creates a new, empty vector.

SharedVector

slint::SharedVector< T >::SharedVector(std::initializer_list< T > args)

Creates a new vector that holds all the elements of the given std::initializer_list ↗ args.

SharedVector

explicit slint::SharedVector< T >::SharedVector(size_t size)

Creates a vector of a given size, with default-constructed data.

SharedVector

explicit slint::SharedVector< T >::SharedVector(size_t size, const T &value)

Creates a vector of a given size, initialized with copies of the value.

SharedVector

slint::SharedVector< T >::SharedVector(InputIt first, InputIt last)

Constructs the container with the contents of the range [first, last).

SharedVector

slint::SharedVector< T >::SharedVector(const SharedVector &other)

Creates a new vector that is a copy of other.

~SharedVector

slint::SharedVector< T >::~SharedVector()

Destroys this vector. The underlying data is destroyed if no other vector references it.

operator=

SharedVector & slint::SharedVector< T >::operator=(const SharedVector &other)

Assigns the data of other to this vector and returns a reference to this vector.

operator=

SharedVector & slint::SharedVector< T >::operator=(SharedVector &&other)

Move-assign’s other to this vector and returns a reference to this vector.

cbegin

const T * slint::SharedVector< T >::cbegin() const

Returns a const pointer to the first element of this vector.

cend

const T * slint::SharedVector< T >::cend() const

Returns a const pointer that points past the last element of this vector. The pointer cannot be dereferenced, it can only be used for comparison.

begin

const T * slint::SharedVector< T >::begin() const

Returns a const pointer to the first element of this vector.

end

const T * slint::SharedVector< T >::end() const

Returns a const pointer that points past the last element of this vector. The pointer cannot be dereferenced, it can only be used for comparison.

begin

T * slint::SharedVector< T >::begin()

Returns a pointer to the first element of this vector.

end

T * slint::SharedVector< T >::end()

Returns a pointer that points past the last element of this vector. The pointer cannot be dereferenced, it can only be used for comparison.

size

std::size_t slint::SharedVector< T >::size() const

Returns the number of elements in this vector.

empty

bool slint::SharedVector< T >::empty() const

Returns true if there are no elements on this vector; false otherwise.

operator[]

T & slint::SharedVector< T >::operator[](std::size_t index)

This indexing operator returns a reference to the `index`th element of this vector.

operator[]

const T & slint::SharedVector< T >::operator[](std::size_t index) const

This indexing operator returns a const reference to the `index`th element of this vector.

at

const T & slint::SharedVector< T >::at(std::size_t index) const

Returns a reference to the `index`th element of this vector.

push_back

void slint::SharedVector< T >::push_back(const T &value)

Appends the value as a new element to the end of this vector.

push_back

void slint::SharedVector< T >::push_back(T &&value)

Moves the value as a new element to the end of this vector.

clear

void slint::SharedVector< T >::clear()

Clears the vector and removes all elements. The capacity remains unaffected.

Friends

operator==

bool operator==(const SharedVector &a, const SharedVector &b)

Returns true if the vector a has the same number of elements as b and all the elements also compare equal; false otherwise.
