把类型强制转换当作一种断言，把不变量当做说明该断言为true的原因的参数。
Think of a cast as a kind of assertion and the invariants as arguments for why the assertion is true.
例如，通过使用类型名称可以将一个值强制转换为另一种类型，就象是一个函数一样。
For example, a value can be cast to another type by using the type name as if it were a function. So you could cast a value to an unsigned integer using the code fragment in Listing 12.
另一个例子，在调用宿主对象的函数时，如何进行类型强制转换，这也是没有规定的。
Another example is that it's not explained how types are coerced when calling functions on host objects. For example, when you do.

With Groovy and its support for duck-typing, there is no casting involved.
如上所述，Route节点对表达式求值，结果将强制转换为布尔值，以生成真或假的测试条件。
As described above, the Route node evaluates an expression, the result of which is then cast as a Boolean to produce a true or false test condition.
若要执行强制转换，请在要转换的值或变量前面的圆括号中指定要强制转换到的类型。
To perform a cast, specify the type that you are casting to in parentheses in front of the value or variable to be converted.
例如，如果用户不知道在某些情况下需要包装，则可能会在对返回对象进行强制转换时发出此消息。
For example, if the user does not understand that wrappers are needed for some scenarios then this will be sent on the return object cast.
注意：您需要强制转换返回类型 ―getValue返回一个Object 类型的对象。
Note that you need to cast the return type -- getValue returns an object of type Object.
如果看到关于强制转换到无符号格式的错误消息，不必惊慌，因为这实际上并不是错误行为。

简言之，这些方法的本质总是使您确信代码块内部的不变量会确保代码块中的任何类型强制转换都将成功。
In short, the moral to this story is to always convince yourself that the invariants inside a code block ensure that any casts in the block will always succeed.
