Member Function Documentation

back() [1/2]

template<class T >

T & wpi::circular_buffer< T >::back ( )

inline

Returns value at back of buffer.

If there are no elements in the buffer, calling this function results in undefined behavior.

back() [2/2]

template<class T >

const T & wpi::circular_buffer< T >::back ( ) const

inline

Returns value at back of buffer.

If there are no elements in the buffer, calling this function results in undefined behavior.

begin() [1/2]

template<class T >

iterator wpi::circular_buffer< T >::begin ( )

inline

begin() [2/2]

template<class T >

const_iterator wpi::circular_buffer< T >::begin ( ) const

inline

cbegin()

template<class T >

const_iterator wpi::circular_buffer< T >::cbegin ( ) const

inline

cend()

template<class T >

const_iterator wpi::circular_buffer< T >::cend ( ) const

inline

emplace_back()

template<class T >

template<class... Args>

void wpi::circular_buffer< T >::emplace_back ( Args &&...  args )

inline

Push a new value onto the back of the buffer that is constructed with the provided constructor arguments.

The value at the front is overwritten if the buffer is full.

emplace_front()

template<class T >

template<class... Args>

void wpi::circular_buffer< T >::emplace_front ( Args &&...  args )

inline

Push a new value onto the front of the buffer that is constructed with the provided constructor arguments.

The value at the back is overwritten if the buffer is full.

end() [1/2]

template<class T >

iterator wpi::circular_buffer< T >::end ( )

inline

end() [2/2]

template<class T >

const_iterator wpi::circular_buffer< T >::end ( ) const

inline

front() [1/2]

template<class T >

T & wpi::circular_buffer< T >::front ( )

inline

Returns value at front of buffer.

front() [2/2]

template<class T >

const T & wpi::circular_buffer< T >::front ( ) const

inline

Returns value at front of buffer.

operator=() [1/2]

template<class T >

circular_buffer & wpi::circular_buffer< T >::operator= ( circular_buffer< T > &&  )

default

operator=() [2/2]

template<class T >

circular_buffer & wpi::circular_buffer< T >::operator= ( const circular_buffer< T > &  )

default

operator[]() [1/2]

template<class T >

T & wpi::circular_buffer< T >::operator[] ( size_t  index )

inline

Returns

Element at index starting from front of buffer.

operator[]() [2/2]

template<class T >

const T & wpi::circular_buffer< T >::operator[] ( size_t  index ) const

inline

Returns

Element at index starting from front of buffer.

pop_back()

template<class T >

T wpi::circular_buffer< T >::pop_back ( )

inline

Pop value at back of buffer.

If there are no elements in the buffer, calling this function results in undefined behavior.

pop_front()

template<class T >

T wpi::circular_buffer< T >::pop_front ( )

inline

Pop value at front of buffer.

If there are no elements in the buffer, calling this function results in undefined behavior.

push_back()

template<class T >

void wpi::circular_buffer< T >::push_back ( T  value )

inline

Push a new value onto the back of the buffer.

The value at the front is overwritten if the buffer is full.

push_front()

template<class T >

void wpi::circular_buffer< T >::push_front ( T  value )

inline

Push a new value onto the front of the buffer.

The value at the back is overwritten if the buffer is full.

reset()

template<class T >

void wpi::circular_buffer< T >::reset ( )

inline

Empties internal buffer.

resize()

template<class T >

void wpi::circular_buffer< T >::resize

(

size_t

size

)

Resizes internal buffer to given size.

size()

template<class T >

size_t wpi::circular_buffer< T >::size ( ) const

inline

Returns number of elements in buffer.
