为什么增加另一种调用字节码呢？
此警告意味着在调用字符串串联函数时，所传递的表示串联字符数的值可能不正确。
This warning indicates that a call to a string concatenation function is probably passing an incorrect value for the number of characters to concatenate.
此示例中的输入是一个简单的字符串，因此将使用字符串填充参数，并将其传递给调用函数。
The input in this example is a simple string, so you populate the argument array with a string and pass it to the invoke function.
尽管使用字符串变量更容易，但是如果通过远程函数调用发送动态sql，可能需要使用内部表。
Although using a string variable is easier, you might need to use an internal table if a remote function call sends the dynamic SQL code.
从此开始，根据构架，为执行从用户缓冲区到内核缓冲区的零拷贝(不可用字节)而进行一个调用。
From here, depending on architecture, a call is made to copy from the user buffer to a kernel buffer with zeroing (of unavailable bytes).
使用字符串“shutdown”来调用setShutdownDatabase方法，然后需要调用getConnection 来执行关闭操作。
The setShutdownDatabase method is called with the string "shutdown", and then a call to getConnection is required to actually perform the shutdown.
清单1显示了D trace脚本的一个简单例子，它计算每个进程发出的系统调用的数量(注意，使用字典将计数和进程关联起来)。
Listing 1 shows a simple example of a DTrace script that counts the number of system calls made by each process. (Note the use of the dictionary to associate counts with processes).
这使得调用方在任何时候都能使用字段，即使类没有任何实例。
This makes the field available to callers at any time, even if no instance of the class exists.
可以使用字符串(实例)方法来操作任何属性值，还可以调用许多系统类的静态方法。
You can use string (instance) methods to operate on any property value, and you can call the static methods of many system classes.
