All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class DelayedBuffer
extends ResizeableBuffer

Unlike parent's, this buffer deletes old elements and give priority to the newly set elements. The Simple and Resizeable buffre only sets new values if possible, this buffer always takes in account new values, even if old ones are dropped in the process. Also, setSlice will bound the buffer size.

Field Detail

delay

protected int delay

Apparent number of index in the buffer. The buffer may actually contain more elements for optimization purposes, but will indicate this number when asked for start and end index.
