本文整理了Java中com.google.common.reflect.TypeToken.getTypes()方法的一些代码示例，展示了TypeToken.getTypes()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TypeToken.getTypes()方法的具体详情如下：
包路径：com.google.common.reflect.TypeToken
类名称：TypeToken
方法名：getTypes

TypeToken.getTypes介绍

[英]Returns the set of interfaces and classes that this type is or is a subtype of. The returned types are parameterized with proper type arguments.

Subtypes are always listed before supertypes. But the reverse is not true. A type isn't necessarily a subtype of all the types following. Order between types without subtype relationship is arbitrary and not guaranteed.

If this type is a type variable or wildcard, upper bounds that are themselves type variables aren't included (their super interfaces and superclasses are).
[中]返回此类型是或是其子类型的接口和类的集合。返回的类型使用适当的类型参数进行参数化。
子类型总是列在超类型之前。但事实并非如此。类型不一定是以下所有类型的子类型。没有子类型关系的类型之间的顺序是任意的，不能保证。
如果该类型是类型变量或通配符，则不包括本身是类型变量的上限（它们的超级接口和超类是）。
