public class CircularBuffer
extends java.lang.Object

CircularQueue It implements a circular FIFO queue of references to Objects.

构造方法摘要

CircularBuffer(int n)
create a queue with max number of elements

方法摘要

boolean	canRead() returns true if read() would succeed
boolean	canWrite() returns true if getEmptyObject() would succeed
void	error() error dump
Buffer	getEmptyBuffer() returns empty buffer object to put data in
boolean	lockedRead()
boolean	lockedWrite()
Buffer	peek() Gets frame with valid buffer from the queue
void	print()
Buffer	read() Gets frame with valid buffer from the queue
void	readReport() indicates that the latest read frame is no longer in use
void	reset() reset the queue
void	writeReport() indicates that latest Object returns to the queue we removed writeReport(false), since we have the mechanism in javax.media.Buffer (discard).
