Function Documentation

all_of()

template<typename Container>

bool collection_utils::all_of

(

const Container &

c

)

Check if all elements in the container evaluate to true.

Elements are cast to bool before evaluation.

Template Parameters

Container

Type of container supporting begin() and end().

Parameters

c	Container to check.

Returns

true if all elements are truthy, false otherwise.

any_of()

template<typename Container>

bool collection_utils::any_of

(

const Container &

c

)

Check if any element in the container evaluates to true.

Elements are cast to bool before evaluation.

Template Parameters

Container

Type of container supporting begin() and end().

Parameters

c	Container to check.

Returns

true if at least one element is truthy, false otherwise.

for_each_in_vector() [1/2]

template<typename T, typename Func>

void collection_utils::for_each_in_vector	(	const std::vector< T > &	vec,
		Func	func )

Apply a function to each element of a read-only vector.

Template Parameters

T	Type of elements in the vector.
Func	Type of the function to apply. Must be callable with const T&.

Parameters

vec	Vector whose elements will be processed.
func	Function to apply to each element.

for_each_in_vector() [2/2]

template<typename T, typename Func>

void collection_utils::for_each_in_vector	(	std::vector< T > &	vec,
		Func	func )

Apply a function to each element of a modifiable vector.

Template Parameters

T	Type of elements in the vector.
Func	Type of the function to apply. Must be callable with T&.

Parameters

vec	Vector whose elements will be processed.
func	Function to apply to each element.

join_all_vectors()

template<typename T>

std::vector< T > collection_utils::join_all_vectors

(

const std::vector< std::vector< T > > &

vectors

)

Concatenate a list of vectors into a single vector.

Template Parameters

T	Type of elements in the vectors.

Parameters

vectors

A vector of vectors to join.

Returns

A new vector containing all elements from all input vectors in order.

join_vectors()

template<typename T>

std::vector< T > collection_utils::join_vectors	(	const std::vector< T > &	v1,
		const std::vector< T > &	v2 )

Concatenate two vectors into a single vector.

Template Parameters

T	Type of elements in the vectors.

Parameters

v1	First vector.
v2	Second vector.

Returns

A new vector containing all elements from v1 followed by all elements from v2.

map_vector()

template<typename T, typename Func>

auto collection_utils::map_vector	(	const std::vector< T > &	vec,
		Func	func )

Transform a vector by applying a function to each element.

Template Parameters

T	Type of input elements.
Func	Type of the function to apply. Must be callable with const T&.

Parameters

vec	Input vector.
func	Function to apply to each element.

Returns

A new vector where each element is the result of applying func to the corresponding input element.
