public static Pointcut intersection(Pointcut pc1,
    Pointcut pc2)

Match all methods that both the given pointcuts match.

    Method method,
    Class targetClass,
    Object[] args)

}

Perform the least expensive check for a pointcut match.

}

Match all methods that either (or both) of the given pointcuts matches.
