If you need another data type such as integer, floating point, or Boolean value, you will have to parse the string using the appropriate wrapper class.

如果需要其他的数据类型，比如说整数、浮点数或者布尔值，必须使用相应的包装器类来解析字符串。

Primitive float type and wrapper class float have different comparison behavior.

There is a POID class, a simple wrapper for the POID value, which insulates our APIs from the actual value type (primitive long in this case).

还有一个poid类，它是poid值的简单包装器，它使API与实际的值类型相分离(在这里是最初为long)。
