Class RingBufferIterator

java.lang.Object
  |
  +--com.grandcentral.appstats.calculators.RingBufferIterator

All Implemented Interfaces:

BufferIterator

public class RingBufferIterator

extends java.lang.Object

implements BufferIterator

Iterates either forwards or backwards over the wrapped buffer in a RingBuffer, starting at the oldest value and working forwards. Like other list iterators, you MUST make sure nothing writes to the buffer while using this Iterator. Will throw a ConcurrentModificationException if it detects that the underlying RingBuffer has been modified.
