Returns a reference to the last element.

Buffer must not be empty.

template<typename T>

static ConstBuffer<T> ConstBuffer< T >::FromVoid | ( | ConstBuffer< void > | other | ) |
| inline static

Cast a ConstBuffer<void> to a ConstBuffer<T>.

A "void" buffer records its size in bytes, and when casting to "T", the assertion below ensures that the size is a multiple of sizeof(T).

Definition at line 119 of file ConstBuffer.hxx.

template<typename T>

reference_type ConstBuffer< T >::front | ( |  | ) | const
| inline

Returns a reference to the first element.

Buffer must not be empty.

Definition at line 185 of file ConstBuffer.hxx.

constexpr bool ConstBuffer< T >::IsEmpty | ( |  | ) | const
| inline

Definition at line 137 of file ConstBuffer.hxx.

template<typename T>

| inline

Definition at line 133 of file ConstBuffer.hxx.

template<typename T>

void ConstBuffer< T >::MoveFront | ( | pointer_type | new_data | ) |
| inline

Move the front pointer to the given address, and adjust the size attribute to retain the old end address.

Definition at line 254 of file ConstBuffer.hxx.

template<typename T>

static constexpr ConstBuffer ConstBuffer< T >::Null | ( |  | ) |

template<typename T>

void ConstBuffer< T >::pop_back | ( |  | ) |
| inline

Remove the last element (by moving the tail pointer, does not actually modify the buffer).

Buffer must not be empty.

Definition at line 223 of file ConstBuffer.hxx.

template<typename T>

void ConstBuffer< T >::pop_front | ( |  | ) |
| inline

Remove the first element (by moving the head pointer, does not actually modify the buffer).

Buffer must not be empty.

Definition at line 210 of file ConstBuffer.hxx.

template<typename T>

reference_type ConstBuffer< T >::shift | ( |  | ) |
| inline

Remove the first element and return a reference to it.

Buffer must not be empty.

Definition at line 235 of file ConstBuffer.hxx.

template<typename T>

void ConstBuffer< T >::skip_front | ( | size_type | n | ) |
