Method Summary

void	addCoordinates(int frame, java.util.ArrayList<double[]> Xs) Adds or replaces the coordinates in the frame.
void	clearSnake(int frame) Removes the snake from frame, note frames start at 1
boolean	exists(int frame) Checks if snake exists in frame

Constructor Detail

Snake

public Snake(int type)

Creates a new snake does not have any position data

Parameters:

type - could be either an OPEN_SNAKE or a CLOSED_SNAKE for the respective curve types

Snake

public Snake(java.util.ArrayList<double[]> coord,
             int i,
             int type)

Creates a new snake with position data.

Parameters:

coord - xcoordinates

i - frame that the current coordinates correspond too.

type - could be either an OPEN_SNAKE or a CLOSED_SNAKE for the respective curve types

Method Detail

getCoordinates

clearSnake

public void clearSnake(int frame)

Removes the snake from frame, note frames start at 1

Parameters:

frame - the frame to be removed from

isEmpty

public boolean isEmpty()

Checks every frame to see if the snake is too short then returns whether or not there are snakes left

addCoordinates

public void addCoordinates(int frame,
                           java.util.ArrayList<double[]> Xs)

Adds or replaces the coordinates in the frame.
