    • DoubleBuffer2D

      public DoubleBuffer2D(DoubleBuffer2DConsumer target, int capacity)
      Constructs and returns a new buffer with the given target.
      Parameters:
      target - the target to flush to.
      capacity - the number of points the buffer shall be capable of holding before overflowing and flushing to the target.

    • add

      public void add(double x, double y)
      Adds the specified point (x,y) to the receiver.
      Parameters:
      x - the x-coordinate of the point to add.
      y - the y-coordinate of the point to add.

    • addAllOf

      public void addAllOf(DoubleArrayList x, DoubleArrayList y)
      Adds all specified points (x,y) to the receiver.
      Specified by:
      addAllOf in interface DoubleBuffer2DConsumer
      Parameters:
      x - the x-coordinates of the points to add.
      y - the y-coordinates of the points to add.

    • clear

      public void clear()
      Sets the receiver's size to zero. In other words, forgets about any internally buffered elements.

    • flush

      public void flush()
      Adds all internally buffered points to the receiver's target, then resets the current buffer size to zero.
