public class BoundedFifoBuffer extends AbstractCollection implements Buffer, BoundedCollection
The removal order of a BoundedFifoBuffer 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.
The add(Object), remove() and get() operations
all perform in constant time. All other operations perform in linear
time or worse.
Note that this implementation is not synchronized. The following can be
used to provide synchronized access to your BoundedFifoBuffer:
Buffer fifo = BufferUtils.synchronizedBuffer(new BoundedFifoBuffer());
This buffer prevents null objects from being added.
