Member Function Documentation

capacity()

size_t rs2::frame_queue::capacity ( ) const

inline

enqueue()

void rs2::frame_queue::enqueue ( frame  f ) const

inline

enqueue new frame into a queue

Parameters

[in]

f

- frame handle to enqueue (this operation passed ownership to the queue)

operator()()

void rs2::frame_queue::operator() ( frame  f ) const

inline

poll_for_frame()

template<typename T >

std::enable_if<std::is_base_of<rs2::frame, T>::value, bool>::type rs2::frame_queue::poll_for_frame ( T *  output ) const

inline

poll if a new frame is available and dequeue if it is

Parameters

[out]

f

- frame handle

Returns

true if new frame was stored to f

wait_for_frame()

frame rs2::frame_queue::wait_for_frame ( unsigned int  timeout_ms = 5000 ) const

inline

wait until new frame becomes available in the queue and dequeue it

Returns

frame handle to be released using rs2_release_frame
