Detailed Description

Class for creating, writing to and reading from a circular buffer.

Definition at line 52 of file circular_buffer.hpp.

Constructor & Destructor Documentation

CircularBuffer()

CircularBuffer::CircularBuffer ( ROSaicNodeBase *  node, std::size_t  capacity  )

explicit

Constructor of CircularBuffer.

Definition at line 39 of file circular_buffer.cpp.

~CircularBuffer()

CircularBuffer::~CircularBuffer

(

)

Destructor of CircularBuffer.

The destructor frees memory (first line) and points the dangling pointer to NULL (second line).

Definition at line 47 of file circular_buffer.cpp.

Member Data Documentation

capacity_

std::size_t CircularBuffer::capacity_

private

Capacity of the circular buffer.

Definition at line 78 of file circular_buffer.hpp.

data_

uint8_t* CircularBuffer::data_

private

Pointer that always points to the same memory address, hence could be const pointer

Definition at line 81 of file circular_buffer.hpp.

head_

std::size_t CircularBuffer::head_

private

Specifies where we start writing.

Definition at line 72 of file circular_buffer.hpp.

node_

ROSaicNodeBase* CircularBuffer::node_

private

Pointer to the node.

Definition at line 70 of file circular_buffer.hpp.

size_

std::size_t CircularBuffer::size_

private

Number of bytes that have been written but not yet read.

Definition at line 76 of file circular_buffer.hpp.

tail_

std::size_t CircularBuffer::tail_

private

Specifies where we start reading.

Definition at line 74 of file circular_buffer.hpp.
