This class is an implementation of functions interface.
It's consisting of a collection (Array List in our project) of functions.
The class have an array of colors, in which it will draw the functions.
The functions-
It implements all the functions of a collection (size, isEmpty, contains, Iterator, both toArray functions, add,
remove, containsAll,addAll,removeAll,retainAll,clear)
Constructors:
A default constructor that creates an empty new collection
initFromFile- init a new collection of functions from a given file name. IOException if the file does not exists of unreadable (wrong format)
saveToFile- write to a given file name. IOException if the file is not writable
drawFunctions (that gets all the parameters: width, height, rx, ry, resolution)- draws all the functions in the collection in a GUI window using the given parameters for the GUI window and the range & resolution.
width- the width of the window, in pixels
height - the height of the window, in pixels
rx - the range of the horizontal axis
ry- the range of the vertical axis
resolution - the number of samples with in rx: the X_step = rx/resolution
drawFunctions (that reads from a Json file, using Gson)- draws all the functions in the collection in a GUI window using the given JSON file (the file with all the parameters for the GUI window).
- Note: if the file is not readable or in wrong format, the functions should use default values.
Default drawFunctions- draws all the functions using default GUI parameters (width=1000, height= 600, x_Range(-10,10), y_Range (-5,15), resolution -200).
E.g-
For the default values, the output would be:
