    • Constructor Detail

      • XYList

        XYList​(int maxx,
       int maxy)
        Create an instance. It is assumed that (maxx+1)*(maxy+1) does not exceed the capacity of an array.
        Parameters:
        maxx - Maximum x-value (inclusive).
        maxy - Maximum y-value (inclusive).

    • Method Detail

      • getWidth

        int getWidth()
        Gets the width. (x, y) values are stored using y * width + x.
        Returns:
        the width

      • getMaxX

        int getMaxX()
        Gets the maximum X value (inclusive).
        Returns:
        the max X

      • getMaxY

        int getMaxY()
        Gets the maximum Y value (inclusive).
        Returns:
        the max Y

      • add

        void add​(int x,
         int y)
        Adds the value to the list.
        Parameters:
        x - X value.
        y - Y value.

      • get

        int get​(int index)
        Gets the 2D index at the specified index. The index is y * width + x: 
         x = index % width
 y = index / width
        Parameters:
        index - Element index.
        Returns:
        the 2D index

      • size

        int size()
        Gets the number of elements in the list.
        Returns:
        the size

      • isEmpty

        boolean isEmpty()
        Checks if the list size is zero.
        Returns:
        true if empty

      • isFull

        boolean isFull()
        Checks if the list is the maximum capacity.
        Returns:
        true if full
