问在AOP中，同步可以作为一个方面来处理吗？

public abstract aspect ReadWriteLockSynchronizationAspect 
    perthis(readOperations() || writeOperations()) {

    public abstract pointcut readOperations();

    public abstract pointcut writeOperations();

    private ReadWriteLock _lock = new SomeReadWriteLock();

    before() : readOperations() {
        _lock.readLock().acquire();
    }

    after() : readOperations() {
        _lock.readLock().release();
    }

    before() : writeOperations() {
        _lock.writeLock().acquire();
    }

    after() : writeOperations() {
        _lock.writeLock().release();
    }
