Detailed Description

template<typename T>
struct lal::detail::data_array< T >

Wrapper of a C array for autmatic deallocation of memory.

Automatically manage deallocation of memory via destructors.

Constructor & Destructor Documentation

data_array() [1/2]

template<typename T >

lal::detail::data_array< T >::data_array ( const std::size_t  n )

inlinenoexcept

Constructor with size.

Parameters

n

Size.

data_array() [2/2]

template<typename T >

lal::detail::data_array< T >::data_array ( const std::size_t  n, const T &  v  )

inlinenoexcept

Constructor with size.

Parameters

n	Size.
v	Value to initialize the array with.

Member Function Documentation

alloc_data()

template<typename T >

void lal::detail::data_array< T >::alloc_data ( )

inlineprivatenoexcept

Allocate memory for array m_data only when m_size is greater than 0.

at() [1/2]

template<typename T >

T const * lal::detail::data_array< T >::at ( std::size_t  i ) const

inlinenoexcept

Pointer at a specific location of the array.

Parameters

i

Position.

Returns

A constant raw pointer.

at() [2/2]

template<typename T >

T * lal::detail::data_array< T >::at ( std::size_t  i )

inlinenoexcept

Pointer at a specific location of the array.

Parameters

i

Position.

Returns

A non-constant raw pointer.

operator[]() [1/2]

template<typename T >

const T & lal::detail::data_array< T >::operator[] ( const std::size_t  i ) const

inlinenoexcept

Element at position i.

Same as std::vector::operator[]

Returns

A constant reference to the i-th element.

operator[]() [2/2]

template<typename T >

T & lal::detail::data_array< T >::operator[] ( const std::size_t  i )

inlinenoexcept

Element at position i.

Same as std::vector::operator[]

Returns

A non-constant reference to the i-th element.

resize() [1/2]

template<typename T >

void lal::detail::data_array< T >::resize ( std::size_t  new_size )

inlinenoexcept

Resize the array.

Does nothing if new_size is the same as the current size.

Parameters

new_size

The new size of the array.

resize() [2/2]

template<typename T >

void lal::detail::data_array< T >::resize ( std::size_t  new_size, const T &  v  )

inlinenoexcept

Resize-initialize the array.

Resizes and initializes the array in the same function.

Parameters

new_size	New size of the array.
v	Value to initialize the array with.

size()

template<typename T >

std::size_t lal::detail::data_array< T >::size ( ) const

inlinenoexcept

Size of the array.

Imitate the vector::size() method.

Returns

The size of the array.
