Detailed Description

template<typename T, uint32_t BufferSize, typename CounterType = uint32_t>
class mbed::CircularBuffer< T, BufferSize, CounterType >

Templated Circular buffer class.

Note: Synchronization level: Interrupt safe.; CounterType must be unsigned and consistent with BufferSize.

Definition at line 69 of file CircularBuffer.h.

Member Function Documentation

bool empty ( ) const

Check if the buffer is empty.

Returns: True if the buffer is empty, false if not.

Definition at line 261 of file CircularBuffer.h.

bool full ( ) const

Check if the buffer is full.

Returns: True if the buffer is full, false if not

Definition at line 273 of file CircularBuffer.h.

bool peek ( T & data ) const

Peek into circular buffer without popping.

Parameters

data	Data to be peeked from the buffer.

Returns: True if the buffer is not empty and data contains a transaction, false otherwise.

Definition at line 306 of file CircularBuffer.h.

bool pop ( T & data )

Pop from the buffer.

Parameters

data	Container to store the data to be popped from the buffer.

Returns: True if data popped.

Definition at line 172 of file CircularBuffer.h.

CounterType pop	(	T *	dest,
		CounterType	len
	)

Pop multiple elements from the buffer.

Parameters

dest	The array which will receive the elements.
len	The number of elements to pop.

Returns: The number of elements popped.

Definition at line 199 of file CircularBuffer.h.

mbed::Span<T> pop ( mbed::Span< T > dest )

Pop multiple elements from the buffer.

Parameters

dest	The span that contains the buffer that will be used to store the elements.

Returns: The span with the size set to number of elements popped using the buffer passed in as the parameter.

Definition at line 251 of file CircularBuffer.h.

void push ( const T & data )

Push the transaction to the buffer.

This overwrites the buffer if it's full.

Parameters

data	Data to be pushed to the buffer.

Definition at line 93 of file CircularBuffer.h.

void push	(	const T *	src,
		CounterType	len
	)

Push the transaction to the buffer.

This overwrites the buffer if it's full.

Parameters

src	Data to be pushed to the buffer.
len	Number of items to be pushed to the buffer.

Definition at line 115 of file CircularBuffer.h.

void push ( mbed::Span< const T > src )

Push the transaction to the buffer.

This overwrites the buffer if it's full.

Parameters

src	Data to be pushed to the buffer.

Definition at line 162 of file CircularBuffer.h.

void reset ( )

Reset the buffer.

Definition at line 281 of file CircularBuffer.h.

CounterType size ( ) const

Get the number of elements currently stored in the circular_buffer.

Definition at line 293 of file CircularBuffer.h.
