public interface CircularFifoBuffer<T>
```
A CircularFifoBuffer is a first in first out buffer with a fixed size that replaces its oldest element if full. CircularFifoBuffer does NOT accept null elements.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`add(T element)`	Adds element to the `CircularFifoBuffer` and overwrites the oldest element when `isFull()`.
`boolean`	`isEmpty()`	Returns `true` if this `CircularFifoBuffer` contains no elements.
`boolean`	`isFull()`	Returns `true` if this `CircularFifoBuffer` is full.
`int`	`size()`	Returns the number of elements in this `CircularFifoBuffer`.
`io.vavr.control.Option<T>`	`take()`	Retrieves and removes the head of this queue, or returns `Option.None` if this queue is empty.
`io.vavr.collection.List<T>`	`toList()`	Returns a list containing all of the elements in this `CircularFifoBuffer`.

    Returns:
    
    the number of elements in this CircularFifoBuffer
  - isEmpty
```
boolean isEmpty()
```
    Returns true if this CircularFifoBuffer contains no elements.
    
    Returns:
    
    true if this CircularFifoBuffer contains no elements
  - isFull
```
boolean isFull()
```
    Returns true if this CircularFifoBuffer is full.

    true if this CircularFifoBuffer is full
  - toList
```
io.vavr.collection.List<T> toList()
```
    Returns a list containing all of the elements in this CircularFifoBuffer. The elements are copied into an array.
    
    Returns:
    
    a list containing all of the elements in this CircularFifoBuffer
  - add
```
void add(T element)
```

    Parameters:
    
    element - to add
    
    Throws:
    
    java.lang.NullPointerException - if the specified element is null
  - take
```
io.vavr.control.Option<T> take()
