Detailed Description

template<typename BufferT>
class rclcpp::experimental::buffers::RingBufferImplementation< BufferT >

Store elements in a fixed-size, FIFO buffer.

All public member functions are thread-safe.

Definition at line 41 of file ring_buffer_implementation.hpp.

Member Function Documentation

dequeue()

template<typename BufferT >

BufferT rclcpp::experimental::buffers::RingBufferImplementation< BufferT >::dequeue ( )

inlinevirtual

Remove the oldest element from ring buffer.

This member function is thread-safe.

Returns

the element that is being removed from the ring buffer

Implements rclcpp::experimental::buffers::BufferImplementationBase< BufferT >.

Definition at line 84 of file ring_buffer_implementation.hpp.

enqueue()

template<typename BufferT >

void rclcpp::experimental::buffers::RingBufferImplementation< BufferT >::enqueue ( BufferT  request )

inlinevirtual

Add a new element to store in the ring buffer.

This member function is thread-safe.

Parameters

request

the element to be stored in the ring buffer

Implements rclcpp::experimental::buffers::BufferImplementationBase< BufferT >.

Definition at line 64 of file ring_buffer_implementation.hpp.

has_data()

template<typename BufferT >

bool rclcpp::experimental::buffers::RingBufferImplementation< BufferT >::has_data ( ) const

inlinevirtual

Get if the ring buffer has at least one element stored.

This member function is thread-safe.

Returns

true if there is data and false otherwise

Implements rclcpp::experimental::buffers::BufferImplementationBase< BufferT >.

Definition at line 119 of file ring_buffer_implementation.hpp.

is_full()

template<typename BufferT >

bool rclcpp::experimental::buffers::RingBufferImplementation< BufferT >::is_full ( ) const

inline

Get if the size of the buffer is equal to its capacity.

This member function is thread-safe.

Returns

true if the size of the buffer is equal is capacity and false otherwise

Definition at line 132 of file ring_buffer_implementation.hpp.

next()

template<typename BufferT >

size_t rclcpp::experimental::buffers::RingBufferImplementation< BufferT >::next ( size_t  val )

inline

Get the next index value for the ring buffer.

This member function is thread-safe.

Parameters

val	the current index value

Returns

the next index value
