public class CircularFifoBuffer extends BoundedFifoBuffer
The removal order of a
CircularFifoBuffer is based on the
insertion order; elements are removed in the same order in which they
were added. The iteration order is the same as the removal order.
Note that this implementation is not synchronized. The following can be
used to provide synchronized access to your
Buffer fifo = BufferUtils.synchronizedBuffer(new CircularFifoBuffer());
This buffer prevents null objects from being added.
This class is Serializable from Commons Collections 3.1.
