Constructor Detail

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.

Method Detail

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.
