public DoubleBuffer(DoubleBufferConsumer 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 element)
```
    Adds the specified element to the receiver.
    
    Parameters:
    
    element - the element to add.
  - addAllOf
```
public void addAllOf(DoubleArrayList list)
```
    Adds all elements of the specified list to the receiver.
    
    Specified by:
    
    addAllOf in interface DoubleBufferConsumer
    
    Parameters:
    
    list - the list of which all elements shall be added.
  - 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 elements to the receiver's target, then resets the current buffer size to zero.
