Table A-6: Method Calls for c_av_st_video_data Class
Method Call Description
function new();
Constructor
function void copy (c_av_st_video_data c);
Copies object c into this object.
function bit compare (c_av_st_video_data r);
Compares this instance to object r. Returns 1 if
identical, 0 if otherwise.
function void set_max_length(int length);
—
function int get_length();
—
function c_pixel #(BITS_PER_CHANNEL,CHANNELS_
PER_PIXEL) pop_pixel();
Returns a pixel object from the packet in first
in first out (FIFO) order.
function c_pixel #(BITS_PER_CHANNEL,CHANNELS_
PER_PIXEL) query_pixel(int i);
Returns a pixel object from the packet at index
i, without removing the pixel.
function void unpopulate(bit display);
Pops all pixels from the packet, displaying
them if display = 1.
function void push_pixel(c_pixel #(BITS_PER_
CHANNEL, CHANNELS_PER_PEXEL)pixel);
Pushes a pixel into the packet.

objects.
c_pixel #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL)
pixel, new_pixel, r_pixel;
Pixel objects used for storing intermediate
data.
rand int video_length;
