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 interfaceDoubleBuffer2DConsumer
- 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.
