实现一个线程安全的Queue队列
使用装饰者模式实现一个线程安全的Queue队列。
public class SynchronizedQueue<E> implements Queue<E>, Serializable {
private static final long serialVersionUID = -1439242290701194806L;
private final Queue<E> q;
public SynchronizedQueue(Queue<E> q) {
this.q = q;
}
public synchronized boolean add(E e) {
return q.add(e);
}
public synchronized E element() {
return q.element();
}
public synchronized boolean offer(E e) {
return q.offer(e);
}
public synchronized E peek() {
return q.peek();
}
public synchronized E poll() {
return q.poll();
}
public synchronized E remove() {
return q.remove();
}
public synchronized boolean addAll(Collection<? extends E> c) {
return q.addAll(c);
}
public synchronized void clear() {
q.clear();
}
public synchronized boolean contains(Object o) {
return q.contains(o);
}
public synchronized boolean containsAll(Collection<?> c) {
return q.containsAll(c);
}
public synchronized boolean isEmpty() {
return q.isEmpty();
}
public synchronized Iterator<E> iterator() {
return q.iterator();
}
public synchronized boolean remove(Object o) {
return q.remove(o);
}
public synchronized boolean removeAll(Collection<?> c) {
return q.removeAll(c);
}
public synchronized boolean retainAll(Collection<?> c) {
return q.retainAll(c);
}
public synchronized int size() {
return q.size();
}
public synchronized Object[] toArray() {
return q.toArray();
}
public synchronized <T> T[] toArray(T[] a) {
return q.toArray(a);
}
@Override
public synchronized boolean equals(Object obj) {
return q.equals(obj);
}
@Override
public synchronized int hashCode() {
return q.hashCode();
}
@Override
public synchronized String toString() {
return q.toString();
}
}
