Detailed Description

template<typename T>
class CVD::RingBuffer< T >

Implements a ringbuffer based on std::vector.

A ringbuffer is a circular buffer i.e. once the end of the buffer is reached, reading or writing continues from the start of the buffer. The buffer maintains a notion of a 'current' element, which is buffer[0], and one can access elements before this or after this (using [-n] or [n] respectively), as well as advancing the current element slot by calling advance()

Parameters:

T

The data type held by the buffer

Member Function Documentation

template<typename T>

void CVD::RingBuffer< T >::resize

(

int

size

)

[inline]

Resize the buffer.

Parameters:

size

The size of the ringbuffer

Definition at line 60 of file ringbuffer.h.

template<typename T>

int CVD::RingBuffer< T >::size

(

)

const [inline]

What is the size of the buffer?

template<typename T>

T& CVD::RingBuffer< T >::operator[]

(

int

i

)

[inline]

Access an element from the ringbuffer.

The [0] element is the current element, and one can use [-n] to access previous values in the ringbuffer (up to a limit of -size(), naturally).

Parameters:

i

The element number

template<typename T>

const T& CVD::RingBuffer< T >::operator[]

(

int

i

)

const [inline]

Access an element from the ringbuffer.

The [0] element is the current element, and one can use [-n] to access previous values in the ringbuffer (up to a limit of -size(), naturally).

Parameters:

i

The element number

Definition at line 81 of file ringbuffer.h.

template<typename T>

void CVD::RingBuffer< T >::advance

(

int

n = 1

)

[inline]

Step the current element on by one.

Parameters:

n

The number of slots to advance by (default is 1)
