有界缓存实现基类
public abstract class BaseBoundedBuffer<V>
{
private final V[] buf;
private int tail;
private int head;
private int count;
@SuppressWarnings("unchecked")
protected BaseBoundedBuffer(int capacity)
{
this.buf = (V[])new Object[capacity];
}
protected synchronized final void doPut(V v)
{
buf[tail] = v;
if (++tail == buf.length)
{
tail = 0;
}
++count;
}
protected synchronized final V doTake()
{
V v = buf[head];
buf[head] = null;
if (++head == buf.length)
{
head = 0;
}
--count;
return v;
}
public synchronized final boolean isFull()
{
return count == buf.length;
}
public synchronized final boolean isEmpty()
{
return count == 0;
}
}
补充:综合编程 , 其他综合 ,
