Detailed Description

template<typename T, int LENGTH>
class LvArray::StackBuffer< T, LENGTH >

This class implements the Buffer interface using a c-array.

Template Parameters

T	type of data that is contained in the buffer. T must be both trivially copyable and trivially destructable.
LENGTH	the length of the buffer.

Note: Unlike the standard Buffer classes the StackBuffer does not permit making shallow copies.; The parent class provides the default execution space related methods.

Constructor & Destructor Documentation

◆ StackBuffer() [1/3]

template<typename T , int LENGTH>

constexpr LvArray::StackBuffer< T, LENGTH >::StackBuffer ( bool = true )

inline

Constructor for creating an empty/uninitialized buffer.

Note: For the StackBuffer an uninitialized buffer is equivalent to an empty buffer.

Definition at line 56 of file StackBuffer.hpp.

◆ StackBuffer() [2/3]

template<typename T , int LENGTH>

constexpr LvArray::StackBuffer< T, LENGTH >::StackBuffer	(	StackBuffer< T, LENGTH > const &	src,
		std::ptrdiff_t
	)

inline

Sized copy constructor, creates a deep copy.

Parameters

src	The buffer to be coppied.

Definition at line 64 of file StackBuffer.hpp.

◆ StackBuffer() [3/3]

template<typename T , int LENGTH>

template<typename _T = T, typename = std::enable_if_t< std::is_const< _T >::value >>

constexpr LvArray::StackBuffer< T, LENGTH >::StackBuffer ( StackBuffer< std::remove_const_t< T >, LENGTH > const & src )

inline

Create a copy of src with const T.

Template Parameters

_T	A dummy parameter to allow enable_if, do not specify.

Parameters

src	The buffer to copy.

Definition at line 75 of file StackBuffer.hpp.

Member Function Documentation

◆ capacity()

template<typename T , int LENGTH>

constexpr std::ptrdiff_t LvArray::StackBuffer< T, LENGTH >::capacity ( ) const

inline

Returns: Return the capacity of the buffer.

Definition at line 103 of file StackBuffer.hpp.

◆ data()

template<typename T , int LENGTH>

constexpr T* LvArray::StackBuffer< T, LENGTH >::data ( ) const

inline

Returns: Return a pointer to the beginning of the buffer.

Definition at line 110 of file StackBuffer.hpp.

◆ free()

template<typename T , int LENGTH>

constexpr void LvArray::StackBuffer< T, LENGTH >::free ( )

inline

Free the data in the buffer but does not destroy any values.

Note: For this class this is a no-op since T must be trivially destructable.

Definition at line 96 of file StackBuffer.hpp.

◆ operator[]()

template<typename T , int LENGTH>

template<typename INDEX_TYPE >

constexpr T& LvArray::StackBuffer< T, LENGTH >::operator[] ( INDEX_TYPE const i ) const

inline

Template Parameters

INDEX_TYPE the type used to index into the values.

Returns: The value at position i .

Parameters

i	The position of the value to access.

Note: No bounds checks are performed.

Definition at line 121 of file StackBuffer.hpp.

◆ reallocate()

template<typename T , int LENGTH>

void LvArray::StackBuffer< T, LENGTH >::reallocate	(	std::ptrdiff_t const	size,
		std::ptrdiff_t const	newCapacity
	)

inline

Notionally this method reallocates the buffer, but since the StackBuffer is sized at compile time all this does is check that newCapacity doesn't exceed LENGTH.

Parameters

size	The current size of the buffer, not used.
newCapacity	the new capacity of the buffer.
